3.8 Address Offset

IR38060 uses an address resistor to set the I2C and PMBus address. The address resistor is used tochange the I2C and PMBus offset from +0 to +16. The offset is added to the bases I2C and PMBusoffset which are pre-programmed in the IR38060 to 0x10h and 0x40h respectively. Below is a tablelisting what resistance to use for a speficied offset.

3.9 Synchronizing Switching Frequency

Users can synchronize the macros to a single or multiple clock signals using the RT/Sync pin. IR38060and IR3892 can synchronize to an appropriate clock signal applied to the device. This feature is usefulwhen trying to filter out noise. The switching frequency can be set to an appropriate frequency and thenfiltered out. The six IR38060 Rt/Sync pins are routed to the XMC headers to allow a XMC controller todetermine the switching frequency and phase shift of each IR38060 rail.

When synchronizing switching frequencies, the clock signal should be six times greater than the highestcross over frequency to keep the rail stable. Crossover frequencies are showing in the bode plots underthe macro section.

Evaluation Board

4 Evaluation Board

The performance and details of the different portions of the evaluation board will be reviewed in thefollowing sections. The board will separated into Power/Miscellaneous, six IR38060 Macros and oneIR3892 Macro. Schematics, bill of materials (BOM), waveforms, efficiency and thermal image areprovided.

4.1 Macro Schematics

The evaluation board simplifies the rail design by building on two macro schematics. There is aschematic for IR38060 macro and a schematic the IR3892 macro. The IR38060 macro schematic Macrocan be used for voltage between 0.5V and 2.0V. The IR3892 macro schematic can be used from 0.5V tothe maximum allowed duty cycle. The schematics can adapt to other voltages and specifications byupdating the components. IR38060 and IR3892 macro schematics are shown below.

4.2 Macro Layout

The evaluation board is comprised of six layers of 2oz copper and FR4 material. The layouts of the railsare based off the IR38060 macro layout or IR3892 macro layout. These layouts offer the user quicklayout solutions and help the user approximate the area needed. The top layer and bottom layer of theIR38060 and IR3892 macros are shown below.

4.3 Macro Components

Components in the macro can be changed. Inductors, input capacitors and output capacitors are criticalcomponent that are usually changed. There are guidelines for changing these components to ensurethe components selected have the proper rating and parameter values.

4.3.1 Inductor

The user can substitute the Bourns SRP5030T-1R0M inductor with another comparable inductor. Thereplacement part should meet or exceed the IDC, ISAT and the size parameters of the proposedinductor. A few possible inductor options are listed in the table below. Some adjustment to the layoutmay be required to fit the inductor.

4.3.2 Output Capacitor

Output capacitor can be substitute for another part, but the de-rate value and ESR should need tomatch. The capacitance of a ceramic capacitor depends on the voltage across the capacitor and thevoltage ripple applied. In most cases, the value is reduces as the voltage increases and the ripple getssmaller. The macros are design with ceramic caps which have a low ESR values, so it will be easier tosubstitute the proposed cap with another brand or model of ceramic caps to mitigate the effect of thezero formed from the ESR.

4.3.3 Input Capacitors / Filter

Changing input capacitors is possible. Input capacitance is usually comprised of ceramiccapacitors whose capacitance is dependent on the input voltage/DC biasing. The ceramic capacitor isrequired to have the proper voltage rating and the derated capacitance value should maintain a properinput voltage ripple.

Input filters with a bead or inductor are occasionally used. Input filters can alter the response andstability of the rail. If an input filter is added to the macro or the supply to the macro, bode plotmeasurement should be checked.
