AP1 MODULE HANDLING CONSIDERATIONS
GENERAL DESCRIPTION
RO DC-DC and AC-DC converter modules have proven to be extremely rugged and aredesigned to meet MIL-STD-810D requirements.Also, once they are installed properly on aprinted circuit board, they can take all the normal mechanical forces for circuit boardsand circuit board mounted components.Reasonable care must exercised, however, during all handling of converter modules, to prevent mechanical damage to the case or the electrical terminal pins.
IMPLEMENTATION
STORAGEModules should be kept in their original ship-ping containers to provide adequate protectionuntil inserted into printed circuit boards.
INSTALLATION INTO PRINTED CIRCUIT BOARDReasonable care must be exercised wheninserting the pins of a module into the holes or sockets of a printed circuit board during production or prototype fabrication. The pinsmust all be properly aligned with the holes orsockets before pressure is evenly exerted tothe surface of the module to seat it onto theboard. Otherwise, overstressed or bent pinscould result in external pin breakage, internaldamage, or degradation of the module.
REMOVAL FROM PRINTED CIRCUIT BOARDIn soldered applications, solder must be carefully removed from the pin/pad connec-tions and each pin must be observed to bemechanically free from its pad. Once the solder is adequately removed, or for socketapplications, the module must be removedusing both hands, one on either end of themodule, to carefully lift the module evenly
off the board. While the pins are clearing thesockets or circuit board holes, the plane of the module baseplate must remain in parallelwith the plane of the circuit board. Otherwise,the pins may be over stressed or bent resultingin degradation or failure.
SHIPMENT OF MODULESIn the event that individual modules areshipped as a component and not in a circuitboard assembly, adequate protection must be provided to the pins to prevent damage.Utilization of the original plastic shipping tube from RO is recommended.

GENERAL DESCRIPTION
RO DC-DC and AC-DC converter modules have proven to be extremely rugged, and aredesigned to meet MIL-STD-810D require-ments. Also, once they are installed properlyon a printed circuit board, they can take all thenormal mechanical forces for circuit boardsand circuit board mounted components.Reasonable care must be exercised, however,during the design and fabrication of modulesinto power supply assemblies to preventexcess stress that could cause mechanicaldamage to the case or the electrical terminalpins.
IMPLEMENTATION
DESIGNGood mechanical engineering practices mustbe observed in designing modules into powersupply assemblies to prevent excess stress orbending forces on the modules and their elec-trical terminal pins. Circuit board holes andsockets must be properly located and mechan-ical attachment to heat sinks and circuit boardsmust be designed to prevent excess shear,compression, or tensile forces on the pins.(See AP-19, Hole Dimensions and SocketInformation.)
AP2 MECHANICAL MOUNTING CONSIDERATIONSCONTINUED
ASSEMBLYGood manufacturing procedures must beobserved in assembling modules into powersupply assemblies to prevent excess stress onthe modules or pins. Reasonable care must beexercised in inserting (and removing) modulesfrom printed circuit boards (See AP-1, ModuleHandling Considerations).
In particular, care must be exercised in applications where a single heat sink isattached to more than one module in a sol-dered application. If possible, the heat sinkshould be assembled to the modules prior to soldering. In situations where this is not possible, care must be exercised to insure thatbolting of the modules to the heat sink follow-ing the soldering operation does not result inexcess stress on the pins. One approach mightbe to fixture the modules during soldering toinsure their baseplates are co-planer and toalso insure that the heat sink is flat and that pin forces are reasonable during and afterassembly.

AP5 OUTPUT VOLTAGE TRIMMING
GENERAL DESCRIPTION
Output voltage trimming allows the user to change the output voltage of the module. This greatly enhances the functionality of modules by allowing a few select, standardmodules to be applied to virtually any applica-tion; regardless of the voltage requirements.This allows module users to reduce the number of models kept in stock.
This application note covers the basics of trimming all RO modules available as of June2002. The format of the trim equation has beenmodi fied so that a single trimming equationcan be used. The equation parameters for aparticular module can be found in the relevantparameters table.
PageQUATTROVERTER Trimming Parameters 59SYNCROVERTER Trimming Parameters 60SUPERVERTER DUAL Trimming Parameters 61SUPERVERTER Trimming Parameters 61PICOVERTER Trimming Parameters 62MICROVERTER Trimming Parameters 63MEGAVERTER Trimming Parameters 63NANOVERTER Trimming Parameters 64
Also covered, are the effects of trimming onvarious performance parameters, applicationideas for trimming, and important precautionsto observe.
IMPLEMENTATION
BASIC TRIMMING CONCEPTSRO uses a simple approach to trimming modules that in most cases allows the moduleto be trimmed with a single external resistor.There are two types of trimming used in ROmodules: Inverting trim, in which the trim signalis summed in with the sense feedback andNon-inverting trim, in which the trim signal isused to modify the reference for the controlcircuits. In either case, to trim the module's
output connect a resistor from TRIM to either+SENSE or -SENSE depending on whetheryou want a lower or higher than nominal output voltage and which type of trimming themodule uses. Each of the following parametertables indicates which type of trimming is usedby the module, whether to connect to +SENSEor –SENSE, and the parameter values to enterin the trim equation. The figures accompanyingthe tables show the appropriate connections.
To calculate the resistor value use the following equation:
Where:
A and B = The equation parameters given in the tables.
| ∆V| = The magnitude of the desired voltagechange from the nominal output voltage. | ∆V| is always positive.
QUATTROVERTER TRIMMINGThe trimming parameters for the QUATTROVERTER modules are given in Table 5a. These parameters, along with thedesired change in output voltage are pluggedinto the trim resistor equation:
The QUATTROVERTER modules use a non-inverting trim function. To trim the output volt-age UP, connect the trim resistor from TRIM to+SENSE. To trim the output voltage DOWN ,connect the trim resistor from TRIM to -SENSE.These connections are shown in Figure 5a.

Example: An application requires 9A at 26V to drive a RF ampli fier in a cellular transmitter.In this application we could use either a 28Vmodule trimmed down to 26V or a 24V moduletrimmed up to 26V. The 28V module wouldhave a current rating of 9A. The 24V modulehas a power rating of 24V x 10A or 240W. At26V the output current must be limited to 240W/26V=9.23A, which is acceptable for the application. For our example we will choosethe 24V module since it will be more efficient(module efficiency improves when the outputis trimmed up and degrades when the output
is trimmed down) and we don't need the lowercurrent limit. The required trim resistor is:

PERFORMANCE EFFECTS OF OUTPUT TRIMMING
Several of the module performance parameterswill change as the output voltage is trimmed.All speci fications given in the data sheets apply over the guaranteed adjustment range.The specifications of primary concern are: efficiency, output ripple, and output OVP.
Efficiency – The efficiency of a given model will decrease as the output voltage is trimmeddown and increase as the voltage is trimmedup.
Output Ripple – As a percentage of the outputvoltage, the output ripple will increase as thevoltage is lowered and decrease as the voltageis raised.
Output OVP – The OVP set point remains at afixed voltage, independent of output trimming.In most cases the OVP set point is what limitsthe maximum trimmable voltage.
As an additional note the user must pay attention to the current and power ratingswhen trimming the output voltage. All RO converters have a fixed current limit. As theoutput voltage is trimmed down the currentlimit set point remains constant. Therefore, interms of output power, if the unit is trimmeddown the available output power drops proportionally. Likewise, if the output istrimmed up the available power appears to go up, however, do not exceed the maximumrated output power of the module when trimming the output up.

POSSIBLE APPLICATIONS
Eliminating the need for remote sense – Output trimming can be used instead ofremote sense when the load current change is limited and the voltage drop between converter and load is relatively constant.
System testing (margining) – Often, it’s helpfulto test system operation with the supply voltage – usually the +5V logic voltage – setfirst at one extreme, then at the other. Any circuitry that fails to perform properly underthese manufacturer's test conditions might also fail under conditions found in the user'senvironment. Margin testing helps insure trouble-free system operation.
Obtaining non-standard output voltages –When a non-standard output voltage is necessary, it may be available simply by trimming the output voltage of a module withan output voltage that's close to the desiredvoltage. Although the published data sheet limits are valid for the guaranteed adjustmentrange, lower output voltages are commonlyavailable by using the trim function. Contactthe factory for details.
Reducing the number of stocked models –When two output voltages are necessary, such as 24V and 28V, one model may be ableto supply both, using the trim function to setthe lower voltage.
PRECAUTIONS
Connect trim resistor to sense, not to output –The trim resistor(s) should be connected to the sense leads, not to the output leads or tothe load. Otherwise, load current changescould cause the converter’s trimmed outputvoltage to vary.
Noise sensitivity – The TRIM pin is noise sensitive. External resistors (either fixed orvariable) should be located within one cm ofthe converter. If wires are necessary, use twisted or shielded wires.
Output power, output current – If the output voltage is increased, output currentmust be derated to avoid exceeding modulemaximum output power. If the output voltageis decreased, output current is limited to itsmaximum rating and the available outputpower decreases.
Adjustment range limits – In some cases, theoutput voltage can be trimmed outside theguaranteed adjustment range. However, datasheet specifications are only valid within thespecified voltage range.

AP6 REMOTE SENSING
GENERAL DESCRIPTION
The remote sense feature provides excellentregulation at the load rather than at theconverter’s output terminals. It does this bysensing and regulating voltage at the load,compensating for load current IR drops acrossoutput connectors, traces, and cables as wellas “or’ing” diode forward voltage drops.
The remote sense feature will compensate forvoltage drops up to 0.5V or 10% of nominaloutput voltage, whichever is greater. If the totalvoltage drop between output terminals andload exceeds this amount, other designchanges, such as increasing conductor size or decreasing connector resistance, must be taken.
RO has also recommended diodes for or’ingapplications that minimize forward voltagedrop. Please see AP13 for details.
Voltage drops across output series resistance(“IRdrops”) vary with output current. If the load current stays relatively constant, RO recommends using output voltage trim insteadof remote sensing. (See AP5)
(Output voltage trim increases the output voltage by a fixed amount to compensate forIR drops between the module and the load;remote sense increases the output voltagedynamically to compensate for variable IRdrops due to load current changes.)
Voltage drops across or’ing diodes (diodes that isolate one converter’s output from another paralleled converter’s) tend to stay relatively constant with load current variations,but change with diode temperature. RO recommends using remote sense when usingor’ing diodes if precise regulation is needed.
IMPLEMENTATION
The remote sense terminals must always beconnected, either to the output terminals or to the load. Connect -SENSE to -OUT at theload and +SENSE to +OUT at the load asshown in Figure 6a.
To reduce noise susceptibility, parallel anelectrolytic capacitor and small ceramic capacitor across the remote sense terminalswhere they are connected to the load asshown in Figure 6a. (Tantalum may be used inlieu of electrolytic capacitors) Please refer toTable 6-1 for recommended values.
Noise filter capacitors are especially helpfulwhen the remote sense leads are over one foot long.
Figure 6a: Remote sense implementation showing theremote sense leads and filter capacitors connected at the point of load.
When using traces for the remote sense connection, shield the traces by using a ground plane. (See AP18)
When using wires (rather than traces) forremote sense connections, twist the wirestogether to reduce noise pickup, or better, use coax.

Table 6-1: Recommended capacitor values forreducing remote sense noise susceptibility.
Although available on all models, remote senseis most useful for high current (low voltage)models,where the potential IR drops are higher.
PRECAUTIONS
Improper use of the remote sense feature canintroduce noise into the module’s feedbackloop, resulting in output noise or oscillations.There are several ways to minimize remotesense lead noise pickup.
(a) Use shielded and/or twisted leads for remotesensing. Also consider using coax cable.
(b) Use noise fi lter capacitors connected acrossthe remote sense leads at the load. See Figure6a and Table 6-1 for further information.
(c) Use output voltage trim to make up for IR drops instead of remote sense if the loadcurrent does not change appreciably. (See AP5)
If the sense leads fail open circuit, the moduleoutput voltage will rise to the OVP set point. Ifthere is any possibility of this situation, connecta 100W resistor from +OUT to +SENSE, andfrom -OUT to -SENSE.
Be careful not to reverse the sense leads. If reversed, the module will be damaged. Astrodyne recommends using keyed connectors.

AP7 MEASURING LINE AND LOAD REGULATION
GENERAL DESCRIPTION
Line regulation is the module’s ability to maintain a constant output voltage as the line(input) voltage changes. Load regulation is the module’s ability to maintain a constant outputvoltage as the load current changes.
Line and load regulation are two of the mostcommon types of converter measurements.Although straightforward, there are some simple guidelines that will help insure accuratereadings.
To check the module for regulation, measurethe output voltage at the sense pins (+SENSEand -SENSE). There is virtually no current flowing through the sense leads, and consequently no appreciable drop acrossthem. Therefore, measuring at the sense pinsis equivalent to measuring at the point wherethe sense leads are connected to the outputleads.
In contrast, there can be a significant voltagedrop between the module’s output terminalsand the load. This voltage drop, which varieswith load current, can cause erroneous regulation values. The remote sense terminalsshould always be connected to the outputeither at the output terminals or at the load.(Connect -SENSE to -OUT and +SENSE to+OUT.)
Line Regulation: Connect a DVM to the sense terminals. Vary the input voltage fromminimum to maximum. The output voltagechange, as a percentage of nominal outputvoltage, is the line regulation. See Figure 7a.
Figure 7a: Detail of line (input) regulationmeasurement circuit
Load Regulation: Connect a DVM to the senseterminals. Vary the load current from zero tomaximum. The output voltage change, as apercentage of nominal output voltage, is theload regulation. See Figure 7b.

AP8 MEASURING OUTPUT NOISE AND RIPPLE
GENERAL DESCRIPTION
Accurately measuring output noise and ripplerequires a basic understanding of the high frequency nature of noise. Very often, “noise”(as commonly measured) is actually the vectorsum of common and differential-mode noise.
Common mode noise is common to both outputs (that is, to +OUT and -OUT) withrespect to chassis or earth ground. Differentialmode noise is found at one output with respect to the other.
While the system load can be affected by differential mode noise, it is seldom affected bycommon mode noise. The latter is often onlycreated in the process of measuring the former.
Noise can be measured as RMS or peak-to-peak. Low frequency noise with a low peak-to-average ratio is often measured as RMS. Highfrequency spike noise is more meaningfullymeasured with an oscilloscope as peak-to-peaknoise. The following information pertains tomeasuring high frequency spike noise.
IMPLEMENTATION
The preferred test setup includes a customprobe made from a length of RG58 A/U coaxialcable. It is connected to the oscilloscope with aBNC “T” connector, which is terminated with a47W carbon composition resistor in series witha 0.68mF Z5U capacitor. The other end of thecoax is left bare. See Figure 8a.
Measure noise as closely as possible to theconverter ’s output terminals to reduce noisepickup.

USING AN OSCILLOSCOPE PROBE
If an oscilloscope probe must be used, it must be properly prepared for high frequencymeasurements.
The greatest error source is usually theunshielded portion of the oscilloscope probe.Error voltages induced by magnetic radiation in the loop can easily swamp out the actual values. To reduce measurement errors, keepunshielded leads as short as possible.
Prepare the probe for high frequency measure-ments by first removing the clip-on groundwire and the probe body fishhook adapter.Attach a special tip and ground lead assemblyas shown in Figure 8d. These assemblies areavailable from several manufacturers:
• Hewlett Packard• Kikusui• LeCroy
Figure 8d: Prepare oscilloscope probe for high frequencymeasurements by removing the ground clip and fishhookadapter. Slip on a special oscilloscope probe tip and ground lead assembly, and contact the output terminals as shown.
Determine if there is any common mode noiseby simultaneously contacting the probe tip and ground lead to the -OUT pin. Any scopepattern indicates common mode noise, andmust be eliminated before accurate measure-ments can be taken.
To eliminate the noise:• Wrap the oscilloscope probe lead several
times around a large-diameter ferrite toroid.This will act as a balun, or common modeinductor. It increases common mode impedance without significantly increasingdifferential mode impedance.
• Isolate the oscilloscope power source from the line voltage with an isolation transformer, or
• Wrap the power source AC line cord several times around a large-diameter ferritetoroid. This also reduces common mode current.
• Try using another oscilloscope and/or probe
PRECAUTIONS
Do not use the ground lead clipped to mostcommon oscilloscope probes. The loop of wireitself will pick up high frequency radiated noiseand give erroneous readings.

AP10 THERMAL CONSIDERATIONS
GENERAL CONSIDERATIONS
Thermal management is an important part of the system design process. The superiordesigns of RO’s modules make thermal man-agement relatively easy. Their high conversionefficiency minimizes the necessary coolingwhile their small package sizes with large thermal interfaces allow simultaneous reductions in system size and cost, along with substantial improvements in reliability.This application note presents some guidelinesfor good thermal design of systems using RO converters.
MODULE LOSSES
AC-DC and DC-DC modules convert powerfrom an input source into regulated power suitable for the given application. While RO’sconversion efficiencies are high, they are notperfect, and some of the input power is lost asheat in the module; which can be calculatedfrom the following equations:
This equation is derived from the definition of efficiency:
The very first step in all thermal managementdesigns is to estimate the worst case powerdissipation. This can be estimated from themodule efficiency graphs given in the catalog;or for conditions not covered by the graphs, itcan be directly measured.
HEAT REMOVAL
MECHANISMS OF TRANSFERHeat is removed from RO converters through themodule’s baseplate. The baseplate is thermallycoupled to and electrically isolated from all internal components. The goal of good thermaldesign is to transfer heat from the baseplate tothe outside world; thereby keeping the base-plate temperature below the maximum rating.
Heat energy is transferred from warm objectsto cold objects by three fundamental means:
Convection: The transfer of energy through a liquid or gaseous media.
Conduction: The transfer of energy through a solid media.
Radiation: The transfer of energy betweenmasses at different temperatures via predomi-nantly infrared wavelengths.
While all three transfer mechanisms will bepresent in every application, convection is the dominant means of heat transfer in most.However, some consideration should be givento all three transfer means to ensure the cooling design is successful.
BASEPLATE TO HEATSINK INTERFACEIn many applications, heat will be conductedfrom the module to a heatsink, which is thencooled via one of the three mechanisms mentioned above. The interface between theheatsink and the baseplate can be modeled asa “thermal resistance” in series with the dissi-pated power flow. The temperature differentialacross the interface can be considerable ifappropriate measures are not taken. Thesemeasures include controlling the flatness of thetwo surfaces and using a filler material such asthermal compound or Grafoil®. With propercare, the thermal resistance across the inter-face can be less than 0.8 °C·in2/Watt; which fora 3.6” x 2.4” module is less than 0.09°C/Watt.

CONVECTION COOLINGConvection cooling is by far the most popularform of cooling used. In a convection cooledsystem the heat energy is transferred from the module to a nearby body of air either bydirect contact or via a heatsink attached to themodule baseplate. The thermal model for con-vection cooling is shown in Figure 10a. Thebaseplate temperature depends on the internalpower dissipation, the total thermal resistancefrom the baseplate to the ambient air, and theambient air temperature. The interface resist-ance can be minimized as discussed previous-ly. The heatsink-to-air resistance is dependenton a variety of factors including heatsink mate-rial, geometry, and surface finish; as well as airtemperature, air density, and air flow rate.Fortunately, thermal resistance data is availablefor a very wide range of standard heatsinks(from RO, Aavid, Thermaloy, and others) foruse in convection cooled applications.Convection cooling is usually classified intotwo types: natural convection, and forced airconvection.
Figure 10a: Thermal model for convection cooled systems.
Natural convection, also referred to as free airconvection, operates on the principle that airbecomes less dense and rises when it is heated.Cooler more dense air then moves in to take its place and remove additional heat. Free airconvection only works well when there is an
unobstructed path for the air to flow. Since thehot air rises vertically the module and heatsinkfins must be properly oriented in the verticaldirection to maximize airflow. The advantagesof free air convection cooling over forced aircooling include a lower implementation cost(no fans), and higher cooling system reliability.The heatsink volume, however, will have to belarger to achieve the same baseplate tempera-ture as with forced air convection.
Forced air convection can make a big differ-ence in cooling effectiveness. With a suitableheatsink, the heatsink-to-air thermal resistancecan be improved by as much as an order ofmagnitude when compared to natural convec-tion performance. Forced air implies the use of fans. In many applications, fans must beused to achieve some desired combination ofoverall system reliability and packaging density.In other applications, however, fans can’t beconsidered because “dirty” environmentsrequire filters which must be changed regularlyto maintain cooling efficiency. Neglecting tochange a filter, or a failure of the fan may cause the system to shut down.
The process for selecting natural convectionand forced convection heatsinks are essentiallythe same. For forced air systems, however, afan must also be selected to create the requiredairflow, and the airflow must be channeled sothat maximum cooling is achieved.
To calculate the required heatsinking:
1. Determine the worst case power to be dissipated. This should be based upon converterefficiency and worst-case converter power output using the formula given in the sectionon Module Losses.
2. Determine the thermal resistance from the module to the heatsink. An estimate of 0.8 °C·in2/Watt should provide adequatesafety margin. For more accuracy, experimen-tally measure the interface resistance for your application.

3. Determine the required thermal resistancefrom the heatsink to the ambient air.Referencing Figure 10a, we can derive the following formula for heatsink-to-ambient thermal resistance:
where:Maximum acceptable Heatsink-to-ambient thermal resistance
Thermal resistance of the interface between the heatsink and the base plate determined in step 2
Module power dissiption, determined in step 1
Worst case anticipated operating ambient air temperature
Maximum desired baseplate temperature, up to 100°C.
4. For forced air systems estimate the airflowthrough the heatsink. This is a non-trivial taskand is some-what iterative with step 5 becausethe heatsink selected will create back-pressureand will affect the airflow. To convert CFM fandata to LFM use the following formula:
Keep in mind that only the air that flowsbetween the fins contributes to the cooling of the module.
5. Select a heatsink that meets the thermalresistance, cost, and physical dimension con-straints. Keep in mind that every degree that thebaseplate temperature is lowered results in significant improvements in the module relia-bility. You should therefore select the heatsinkwith the lowest possible thermal resistancewithin your constraints. Table 10a shows thethermal resistance of RO’s heatsinks.
Alternatively, steps 4 and 5 can be done in theopposite order if your heatsink constraints aremore severe than your fan constraints, i.e. youcan select the heatsink first, and then pick a fanto get the necessary airflow.
6. Estimate the baseplate temperature using thefollowing formula:
7. Verify the design via measurement. This isthe most important step in the design process.

Table 10a: Thermal resistances of RO heatsinks
When designing the cooling system keep thefollowing in mind:
• Heatsink data for natural convection is almost always given for vertical fin orientation.Orienting the fins in any other direction willimpede the airflow and degrade the coolingeffectiveness significantly. If you can’t use thepreferred orientation then get relevant heatsink performance data from the manufacturer.
• Natural convection depends on air movement caused by air density changes. The manufacturer’s thermal resistance datadepends on unobstructed air movement in-between and around the fins. If the airmovement will be blocked or otherwise affected by the packaging then a larger heatsinkmay be required. In some cases, natural convection cooling may not be useable.
• Radiation cooling can be a significant contributor to natural convection cooled systems. Maximize radiation cooling by usingan appropriate finish on the heatsink, such as black anodize.

• It is not necessary for the heatsink to be the same size as the baseplate. Heatsinks thatare larger than the baseplate can often be usedadvantageously. Especially in applicationswhere the fin height may be limited. Whenusing heatsinks that are larger than the base-plate, select one that has a thick base for betterconduction to the outer fins and derate themanufacturer ’s thermal resistance slightly.
• Several modules can be mounted to a com-mon heatsink, but cooling calculations mustnow take into account the total power dissipa-tion of all the modules. Give consideration tothe possibility of localized overheating if thepower dissipation isn’t uniformly distributed.
TIPS ON MODULE PLACEMENT
Here are some tips to consider when laying outthe system and placing the modules on the PWB:
• Always ensure that the module and heatsinkinterfacing surfaces are flat, smooth, clean, andfree of debris
• Always use a void fi lling material such asthermal compound, thermal pads, or someother thermally conductive, conformable ormalleable material. RO offers precut thermalpads made from GRAFOIL ‚ material. Note: thermal pads are pre-installed on all heatsinks purchased from RO.
• Stagger the modules on the PWB to promote good air flow, to minimize thermalinteraction between modules, and to facilitateeven heat distribution.
• Avoid blocking the air flow to the moduleswith other components.
• Use a heatsink with the fins running in thedirection of the air flow. For natural convectionsystems the air will flow upward in a verticaldirection.

EXAMPLES
A µV48-5 module is being operated with 30A of load current in an ambient of 30 °C. From the efficiency graph in the catalog it has an efficiency of 82%. The module’s losses are then:
The desired baseplate temperature is 75°C anda conservative estimate of the interface thermalresistance is 0.2°C/W. We therefore need aheatsink with a thermal resistance of:
From the catalog we see that the RO 2005heatsink has a thermal resistance of 1.0 °C/Wwith 400 LFM of air flow. The resulting designwill operate at a baseplate temperature of:
PRECAUTIONS
Observe Max. Temperature RatingsWhile the modules will protect themselves ifthe maximum baseplate temperature rating is exceeded, operating above the rating forextended periods of time can reduce the reliability of the module.
Don’t Compress PC Board MaterialDon’t allow the mounting screws for the modules to exert compressive force on thePWB. The PWB material, typically G-10 or FR-4,will cold flow away from the screw and releasethe screw tension. The result can be a loss ofheatsinking.

Included here are answers to some of the questions that our customers askmost frequently.
Q: What is the PWB footprint for the RO modules?
A: RO’s modules are generally smaller than our competition’s modules. The basic, recommended PWB footprints for our modules are shown in Application Note 19,Hole Dimensions and Socket Information.In addition, the outline drawings included in the product data sheets are another goodsource of information for creating customPWB footprints.
Q: How much heatsinking do I need for theRO converters?
A: The amount of heatsinking required is determined by the environment that themodule is placed in, the heat produced inthe module, and the maximum desiredbaseplate temperature. Because RO’s modules are highly efficient the requiredheatsinking is minimal. It may even be possible to operate the modules withoutany additional heatsinking. The thermal performance curves in this catalog weredesigned so that you can quickly determinethe amount of heatsinking required for yourapplication. A more in-depth discussion ofthermal design with the RO modules isavailable in Application Note 10, ThermalConsiderations.
Q: Why is a 1W, 6.2V Zener diode recommended on the Parallel Pin?
A: The Zener diode is recommended for any application that can see more than 6V, induced or applied, on the Parallel Pin.Accidental shorting of the Parallel Pin to a voltage greater than 6V will cause themodule to fail. A 1W, 6.2V Zener diode willprotect against most incidental shorts thatoccur during module testing as well as most externally induced transients thatoccur during operation.
Q: Why do I see 1V spikes on the output of the module?
A: These spikes do not really occur on the output, rather they are mostly the result ofnoise pickup and measurement error in thetest setup used. A common source of noisepickup is the loop created by the ground clip on most standard scope probes.Application Note 8, Noise and RippleMeasurement, discusses how to properlymeasure the output noise and ripple.
Q: Can RO modules be used with no additional components?
A: Yes, in some applications they can. However,bypass capacitors are often required toreduce system noise and achieve propermodule performance. For basic systems, we recommend that pads and traces for thecomponents shown in Figure 1 be includedin the initial PWB layout. The design teamcan then either optimize them for perform-ance or, if performance is good, eliminatethem for cost reduction.
Figure 1
Q: Paralleling De-coupling Modules (PDMs) are great when redundancy is required, but can the RO modules be paralleled without PDMs?
A: Yes, RO modules can be paralleled withoutany external components other than bypassand storage capacitors when redundancy isnot required. An exception to this, however,is the 300V MICROVERTER series; whichrequires a disconnect circuit to ensure anorderly startup. See Application Note 11 formore information.

Q: What is the recommended solder processfor the modules?
A: The recommended solder process is a wave solder process with the solder waveat 260°C. Each pin should be in the wave for5 seconds and the big pins should enter thewave last. Because the modules have a highthermal mass, the preheat cycle must belengthened in order for proper solder wetting of the pins to occur.
Q: Why do the modules sometimes seem tocurrent limit to early?
A: Noise on the Parallel Pin, the Input Pins, or the Output Pins can cause premature current limit in the modules. ApplicationNote 13 Paralleling- Current Sharing, Hot Plug-in, and N+M Redundancy andApplication Note 18 Board LayoutConsiderations and Recommendations provide some preventative and correctivemeasures that can be taken to reduce thenoise. Adding the proper bypass caps tothese pins will usually solve the problem.
Q: Why does the output noise increase when I connect the output return lines of thetriple output module together?
A: As with most multiple output power supplies,common mode noise can be injected fromone output into another causing increasednoise. Adding a small, common mode chokeof about 25µH per leg to each auxiliary out-put, before the common ground connection,will prevent this from occurring. SeeApplication Note 14 for more information.
Q: How does the output good signal function?
A: The output good signal provides an activelow output whenever the sensed outputvoltage is within ±10% of the set outputvoltage;otherwise it appears as an open collector (Vmax = 40V). The signal is referenced to -SENSE (See Figure 2) and

is capable of sinking 15mA typical (8mAminimum). The output low voltage (saturation voltage) is 0.5V or less @ lsink = 1.6mA. The output good signalchanges its state in the range Vsense =±9% to ±11% of Vsetpoint.
Figure 2: Equivalent circuit of the Output Good Signal
Q: How do I use the ON/OFF pin?A: The ON/OFF pin may be used to turn the
module off and on remotely using a low level signal. When ON/OFF is pulled low (<1V @4mA, referenced to -Vin), the module is turned off. All that is required to interface the ON/OFF signal to the other circuits is a few external components as shown in Figure 3. Additional ways to use the ON/OFF pin are shown in Application Note 4, Logic On-Off.

Pin Function/Description
AC1, AC2 These are the AC input terminals. The input should be connected to a suitable input filter in order to for the PFC module to perform properly and reliably and to comply with applicable EMI performance standards.
+Out This is the positive output terminal. It should be connected to the positive terminal of the hold up capacitor. The 375 VDC output will appear here w.r.t the –Out terminal. Hold-up capacitor value ranges are provided in the specifications. The hold-
up capacitor must be located in close proximity to the PFC output terminals.
LD ENA This terminal provides logic control to downstream DC/DC converters. The LD ENA signal will be a logic low during PFC start up and will switch logic state (to open collector) upon the PFC output reaching 340 VDC. If AC input power is lost, the LD ENA will again go low when the PFC output drops to 220 VDC. For many RO DC/DC products, it is not necessary to use the LD ENA terminal. Please

see the applications notes or consult the factory for more information.
RSS This terminal is internally connected to inrush control circuitry on model PFC-650U and is N/C on model PFC-650W. Model PFC-650W has a built in inrush limiting resistor whereas for model PFC-650U the resistor must be provided externally. For PFC-650U, connect one end of the inrush limiting resistor to this terminal. The other end of the resistor will be connected to –Out. The external inrush resistor
must be chosen to handle the inrush energy which is determined by the input voltage and hold-up capacitor value selected. The inrush connection diagram provides some specific recommendations. Consult the factory for assistance or additional information on selecting an inrush resistor.
-Out This is the PFC negative output terminal. It should be connected to the negative terminal of the hold up capacitor. For model PFC-650U, connect one end of the inrush resistor to this terminal.
Application Diagrams The connection diagrams below show proper connections between PFC-650 modules, hold-up capacitor, inrush limiting resistor (if required) and DC/DC converters.
For PFC-650W, the inrush limiting resistor is built-in and an external resistor is not required. The resistor is appropriately sized for a maximum input voltage of 180VAC and a maximum external hold-up capacitor value of TBD.
For PFC-650U, an external inrush limiting resistor must be provided and connected as shown in the connection diagram for PFC-650U. A resistor with high surge handling capability should be used. The maximum input voltage, external hold-up capacitor value and temperature must be considered in choosing a resistor. The maximum RMS input voltage and resistor value will determine the maximum inrush current. A resistor value of at least 10 ohms should be chosen. The surge energy in the resistor is that required to charge the hold-up capacitor up to the peak of the line. After that, internal circuitry will both bypass the external resistor with essentially a short circuit and limit additional inrush current to TBD Amps.
See also the Start-up and Shutdown Timing Diagram for additional information.

Unless otherwise stated, these apply for ambient temperature TA=23 ±2°C, nominal input voltage, and rated full load. (1)
NOTES:(1) Refer to the Astrodyne Application Notes for
terms,measurement circuits, and other information.(2) Refer to the Astrodyne Application Notes for information on fusing.
For inrush current, refer to the above.(3) 33 µF capacitor connected to two “Input” pins. Then place
current sensor in series with 12 µH inductor between 33 µF andthe source. The ripple current is measured over 5 Hzto 20 MHz bandwidth (current sensor is located between theconverter input pin and the 12 µH inductor).
(4) Optimum performance is obtained when this power supply isoperated within the minimum to maximum load No damage to module will occur when the output is operated atless than minimum load, but the output voltage may contain alow frequency component that may exceed output noise
.(5) Load regulation is as the output voltage change when
changing load current from maximum to minimum. The voltageis measured at the output pin.
(6) Load Transient Recovery Time is as the time for theoutput to settle from a 50 to 75% or 25% step load change to a1% error band of output voltage (rise time of step = 2µ Sec).
(7) Load Transient Overshoot is as the peak overshootduring a transient as in the Note 6 above.
(8) Noise is measured per the Astrodyne Application Notes. Outputnoise is measured with a 10 µF tantalum capacitor in parallelwith a 0.1 µF ceramic capacitor connected across the output toCMN. Measurement bandwidth is 0-20 MHz.
(9) When an external switch is used, such as open collectorswitch, logic high requires the switch to be high-impedance.Switch leakage currents greater than 20 µA may be totrigger the to the logic-low state.
(10) Most switches would be suitable for logic control, in casethere is a problem, you can make following estimation and thenleave some margin.When open collector is used for logic high, “Open Circuit Voltageat Pin”, “Output Resistance” and “External LeakageCurrent Allowed for Logic High” are used to estimate the highimpedance requirement of open collector.When switch is used for logic low, “Open Circuit Voltage at On/
Pin”, “Output Resistance” and “LOW Logic Level” are usedto estimate the low impedance requirement of switch.
(11) Thermal impedance is tested with the converter mounted verticallyand facing another printed circuit board 1/2 inch away. Ifconverter is mounted horizontally with no obstructions, thermalimpedance is approximately 10 °C/W.If heat sink is needed, apply a very thin layer of thermallyconductive grease on the metal base of converter, then properlytighten the screws.
(12) Water Washability - These DC/DC converters are designed towithstand most solder/wash processes. Careful attention shouldbe used when assessing the applicability in your cmanufacturing process. Converters are not hermetically sealed.
(13) Torque fasteners into threaded mounting inserts at 12 in. oz. orless. Greater torque may result in damage to unit and void thewarranty.

Notes:(1) Refer to the Application Notes for the definition of terms,
measurement circuits, and other information.(2) Refer to the Application Notes for information of fusing.
For inrush current, refer to the specifications above.(3) 33µF capacitor connected between the two “Input” pins. Then
insert current sensor in series with 1.0µH inductor between 100µF and the source. The reflected ripple current is measured over a 5 Hz to 20 MHz bandwidth. (current sensor is located between the converter input pin and the 1.0 µH inductor)
(4) Optimum performance is obtained when this power supply is operated within the minimum to maximum load specifications. No damage to the module will occur when the output is operated at less than minimum load, however, below minimum load the dynamic response will degrade. Operation below minimum load is not recommended.
(5) Load regulation is defined as the output voltage change when changing load current from a maximum to minimum.
(6) Load Transient Recovery Time is defined as the time for the output to settle from a 50% to 75% step load change to a 1% error band (rise time of step = 2µs).
(7) Load Transient Overshoot is defined as the peak overshoot during a transient as defined in the Note 6 above.
(8) Noise is measured per the Application Notes. Output noise is measured with a 10µF tantalum capacitor in parallel with a 0.1µF ceramic capacitor connected across the output pins. Measurement bandwidth is 0-20MHz.
(9) When an external ON/OFF switch is used, such as open collector switch, logic high requires the switch to be high-impedance. Switch leakage currents greater than 10µA may be sufficient to trigger the ON/OFF to the logic-low state.
(10) Most switches would be suitable for the logic ON/OFF control. In case there is a problem you can make the following estimations and then leave some margin.
When open collector is used for logic high, “Open Circuit Voltage at ON/OFF Pin”, “Output Resistance” and “External Leakage Current Allowed for Logic High” are used to estimate the high impedance requirement of open collector.
When switch is used for logic low, “Open Circuit Voltage at ON/OFF Pin”, “Output Resistance” and “LOW Logic Level” are used to estimate the low impedance requirement of the switch.
(11) Thermal impedance is tested with the converter mounted vertically and facing another printed circuit board 1/2 inch away. If converter is mounted horizontally with no obstruction, thermal impedance is approximately 8°C/W.
(12) Water Washability - These DC/DC converters are designed to withstand most solder/wash processes. Careful attention should be used when assessing the applicability in your specific manufacturing process. Converters are not hermetically sealed.
(13) Torque fasteners into threaded mounting inserts at 12 in.lbs. or less. Greater torque may result in damage to unit and void the warranty.
(14) Input impedance on these units needs to be kept to a minimum. The 9-36Vdc DC units need a maximum input impedance of 0.2 Ohms and the 18-75Vdc DC units need a maximum input impedance of 0.8 Ohms. In order to support this requirement, the 9-36Vdc DC units need 25 µF of capacitance (low ESR) for every 1.0 µH of inductance between the power source and the DC/DC converter. The 18-75Vdc DC units need 1.7µF of capacitance (low ESR) for every 1.0 µH of inductance between the power source and the DC/DC converter. Inductance includes all sources and should take into account input power lines.
(15) RoHS Compliance: See Astrodyne Website www.astrodyne.com for the complete
RoHS Compliance statement and Application Notes. The RoHS marking is as follows.
