Thermal Design Example

The thermal resistance, c-a of the required heat sink for the power dissipation, Pd, within the hybrid IC is determined asfollows.

Condition 1: The IC substrate temperature, Tc, must not exceed 125C.

Pd c a + Ta < 125C . . . . . . . . . (1)Ta: Guaranteed ambient temperature for the end product.

Condition 2: The junction temperature, Tj, of each power transistor must not exceed 150C.

Pd c a + Pd/N j c + Ta < 150C . . . . . . . . . (2)N: Number of power transistorsc-a: Thermal resistance per power transistor

However, the power dissipation, Pd, for the power transistors shall be allocated equally among the N transistors.The following inequalities results from solving equations (1) and (2) for c-a.

c a < (125 Ta) /Pd . . . . . . . . . . . . . . . . . . (1)c a < (150 Ta) /Pd j c/N . . . . . . . . . (2)

Values that satisfy these two inequalities at the same time represent the required heat sink thermal resistance.When the following specifications have been stipulated, the required heat sink thermal resistance can be determined fromformulas (1) and (2).

Supply voltage VCC

Load resistance value RL

Guaranteed ambient temperature Ta

[Example]

When the IC supply voltage, VCC, is 32 V and RL is 6 , the IC internal power dissipation, Pd, will be a maximum of72 W for a continuous sine wave signal at 1 kHz, according to the Pd PO characteristics.

For the music signals normally handled by audio amplifiers, a value of 1/8 PO max is generally used for Pd as an estimateof the power dissipation based on this type of continuous signal. (Note that the factor used may differ depending on thesafety standards used.)

That is:

Pd = 48 W (When 1/8 PO max = 6.25 W)

The number of power transistors in the audio amplifier block of these hybrid ICs, N, is 4, and the thermal resistance pertransistor is 2.2C/W. Therefore, the required heat sink thermal resistance for a guaranteed ambient temperature of 50Cwill be as follows.

From formula (1) c a < (125 50) /48< 1.56

From formula (2) c a < (150 50) /48 2.2/4< 1.53

Therefore, 1.53C/W is the required heat sink thermal resistance.

Note that this thermal design example assumes the use of a constant-voltage power supply, and is therefore not a verifieddesign for any particular user's end product.

The heat sink thermal resistance, c-a, required to handle the total power dissipated within this hybrid IC is determined asfollows.

Condition 1: The IC substrate temperature Tc must not exceed 125C.

Pd c a + Ta < 125C ... (1)Ta: Guaranteed ambient temperature for the end product.

Condition 2: The junction temperature of each individual transistor must not exceed 150C.

Pd c a + Pd/N j c + Ta < 150C ... (2)N: Number of power transistors

j-c: Thermal resistance per power transistorWe take the power dissipation in the power transistors to be Pd evenly distributed across those N power transistors.

If we solve for c-a in equations (1) and (2), we get the following inequalities.c a < (125 Ta)/Pd ... (1)c a < (150 Ta)/Pd j-c/N ... (2)

Values that satisfy both these inequalities at the same time are the required heat sink thermal resistance values.

Determining the following specifications allows us to determine the required heat sink thermal resistance frominequalities (1) and (2).

Supply voltage: VCC

Load resistance: RL

Guaranteed ambient temperature: Ta

Example:

Assume that the IC supply voltage, VCC, is 23 V, RL is 6 , and that the signal is a continuous sine wave. In this case,from the Pd PO characteristics, the maximum power will be 103 W for a signal with a frequency of 1 kHz.

For actual music signals, it is usual to use a Pd of 1/8 of POmax, which is the power estimated for continuous signals inthis manner. (Note that depending on the particular safety standard used, a value somewhat different from the value of1/8 used here may be used.)

That is:

Pd = 65 W (when 1/8 POmax is 2.5 W)

The number, N, of power transistors in the hybrid IC's audio amplifier block is 12. Since the thermal resistance, c-a, pertransistor is 3.6C/W, the required heat sink thermal resistance, c-a, for a guaranteed ambient temperature of 50C willbe as follows.

From inequality (1): c a < (125 50)/65< 1.15

From inequality (2): c a < (150 50)/65 3.6/12< 1.23

Therefore, the thermal resistance that satisfies both these expressions at the same time is 1.15C/W.

Note that this thermal design example assumes the use of a constant-voltage power supply, and is only provided as anexample for reference purposes. Thermal designs must be tested in an actual end product.

Impulse noise that occurs at power on and power off can be reduced significantly by using a standby circuit. End product design is made easier by using a limiting resistor *1 to match the control voltage provided by the microcontroller or other control circuit. Standby control can be applied by controlling the current (IST) flowing into the standby pin (pin 23).

OverviewThe STK403-400 series products are audio poweramplifier hybrid ICs that consist of optimally-designeddiscrete component power amplifier circuits that havebeen miniaturized using SANYOs unique insulated metalsubstrate technology (IMST). The adoption of a newly-developed low thermal resistance substrate allows thisproduct to integrate six power amplifier channels in asingle compact package. The adoption of a standby circuitin this device allows it to reduce impulse noisesignificantly as compared to earlier Sanyo products, inparticular, the STK402-*00 series products.

Condition 2: The junction temperature of each transistor must not exceed 150C.

Pd c-a + Pd/N j-c + Ta < 150C ... (2)N: Number of power transistors


If we solve for c-a in equations (1) and (2), we get the following inequalities.c-a < (125 Ta)/Pd ... (1)c-a < (150 Ta)/Pd j-c/N ... (2)


Determining the following specifications allows us to obtain the required heat sink thermal resistance from inequalities(1) and (2).

Supply voltage: VCC

Load resistance: RL


Example:



That is:


The number, N, of power transistors in the hybrid IC's audio amplifier block is 12. Since the thermal resistance, j-c, pertransistor is 3.6C/W, the required heat sink thermal resistance, c-a, for a guaranteed ambient temperature of 50C willbe as follows.

From inequality (1): c-a < (125 50)/85< 0.88

From inequality (2): c-a < (150 50)/85 3.6/12< 0.87

Impulse noise that occurs at power on and power off can be reduced significantly by using a standby circuit. End product design is made easier by using a limiting resistor (*) to match the control voltage provided by the microcontroller or other control circuit. Standby control is available by controlling the current (IST) flowing into the standby pin (pin 23).

If we solve for c-a in equations (1) and (2), we get the following inequalities.c-a < (125 Ta)/Pd ... (1)c-a < (150 Ta)/Pd j-c/N ... (2)


Determining the following specifications allows us to obtain the required heat sink thermal resistance from inequalities(1) and (2).

Supply voltage: VCC

Load resistance: RL


Example:



That is:


The number, N, of power transistors in the hybrid IC's audio amplifier block is 12. Since the thermal resistance, j-c, pertransistor is 3.6C/W, the required heat sink thermal resistance, c-a, for a guaranteed ambient temperature of 50C willbe as follows.

From inequality (1): c-a < (125 50)/105< 0.71

From inequality (2): c-a < (150 50)/105 3.6/12< 0.65

If we define Pd, the total power dissipation on the board when this hybrid IC is in operation, the heat sink thermalresistance, c-a, is determined as follows:

Condition 1: The hybrid IC substrate temperature Tc must not exceed 125C.





If we solve for c-a in equations (1) and (2), we get the following inequalities:c-a < (125 Ta)/Pd ... (3)c-a < (150 Ta)/Pd j-c/N ... (4)


Example:


When VCC = 26V and RL = 6, we get the following expression for the total power dissipation on the board, Pd:Pd = 15W (when 1/8 POmax is 3.8W) ... (5)

The number, N, of power transistors in the hybrid ICs audio amplifier block is 2. Since the thermal resistance, j-c, pertransistor is 3.0C/W, the required heat sink thermal resistance, c-a, for a guaranteed ambient temperature of 50C willbe as follows:

From inequality (3): c-a < (125 50)/15=5.00 ... (6)From inequality (4): c-a < (150 50)/15 3.0/2=5.17 ... (7)

Therefore, the thermal resistance that satisfies both these expressions (6,7) at the same time is 5.0C/W.
