Thermal Design Example

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

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

Pd × θc – a + Ta < 125°C

.........

(1)

Ta: Guaranteed ambient temperature for the end product.

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

Pd × θc – a + Pd/N × θj – c + Ta < 150°C

.........

(2)

N: Number of power transistors θc-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 θc-a.

θc – a < (125 – Ta) /Pd

..................

(1)’

θc – a < (150 – Ta) /Pd – θj – 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 from formulas (1)’ and (2)’.

• Supply voltage — V

CC

• Load resistance value — RL

• Guaranteed ambient temperature — Ta

[Example] When the IC supply voltage, VCC, is ±32 V and RLis 6 Ω, the IC internal power dissipation, Pd, will be a maximum of

72 W for a continuous sine wave signal at 1 kHz, according to the Pd – POcharacteristics. For the music signals normally handled by audio amplifiers, a value of 1/8 POmax is generally used for Pd as an estimate

of the power dissipation based on this type of continuous signal. (Note that the factor used may differ depending on the safety standards used.)

That is:

Pd = 48 W (When 1/8 POmax = 6.25 W)

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

From formula (1)’ θc – a < (125 – 50) /48

< 1.56

From formula (2)’ θc – a < (150 – 50) /48 – 2.2/4

< 1.53

Therefore, 1.53°C/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 verified

design for any particular user's end product.

Thermal Design Example

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

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

Pd × θc – a + Ta < 125°C ... (1) Ta: Guaranteed ambient temperature for the end product.

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

Pd × θc – a + Pd/N × θj – c + Ta < 150°C ... (2) N: Number of power transistors θj-c: Thermal resistance per power transistor

We take the power dissipation in the power transistors to be Pd evenly distributed across those N power transistors. If we solve for θc-a in equations (1) and (2), we get the following inequalities.

θc – a < (125 – Ta)/Pd ... (1)’ θc – a < (150 – Ta)/Pd – θj-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 from

inequalities (1)’ and (2)’.

• Supply voltage: V

CC

• Load resistance: R

L

• Guaranteed ambient temperature: Ta

Example: Assume that the IC supply voltage, VCC, is ±23 V, RLis 6 Ω, and that the signal is a continuous sine wave. In this case,

from the Pd – POcharacteristics, 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 in

this manner. (Note that depending on the particular safety standard used, a value somewhat different from the value of 1/8 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, θc-a, per transistor is 3.6°C/W, the required heat sink thermal resistance, θc-a, for a guaranteed ambient temperature of 50°C will be as follows.

From inequality (1)’: θc – a < (125 – 50)/65

< 1.15

From inequality (2)’: θc – a < (150 – 50)/65 – 3.6/12

< 1.23 Therefore, the thermal resistance that satisfies both these expressions at the same time is 1.15°C/W. Note that this thermal design example assumes the use of a constant-voltage power supply, and is only provided as an

example for reference purposes. Thermal designs must be tested in an actual end product.

Overview

The STK403-400 series products are audio power amplifier hybrid ICs that consist of optimally-designed discrete component power amplifier circuits that have been miniaturized using SANYO’s unique insulated metal substrate technology (IMST). The adoption of a newlydeveloped low thermal resistance substrate allows this product to integrate six power amplifier channels in a single compact package. The adoption of a standby circuit in this device allows it to reduce impulse noise significantly as compared to earlier Sanyo products, in particular, the STK402-*00 series products.

Features

• Series of pin compatible power amplifiers ranging from 30 W/ch to 45 W/ch (10%/1 kHz) devices. The same printed circuit board can be used depending on the output power grade.

• Miniature packages — 78.0 mm × 32.0 mm × 9.0 mm *

*: Not including the pins.

• Output load impedance: RL= 6 Ω

• Allowable load shorted time: 0.3 seconds

• Supports the use of standby and muting circuits.

Maximum Ratings at Ta = 25°C

These products are organized as a series based on their output capacity.

Operating Characteristics at Tc = 25°C, RL= 6 Ω (noninductive load), Rg = 600 Ω, VG = 30 dB

Notes: 1. 1ch drive

2. Unless otherwise noted, use a constant-voltage supply for the power supply used during inspection.

3. The output noise voltage values shown are peak values read with a VTVM. However, an AC stabilized (50 Hz) power supply should be used to minimize the influence of AC primary side flicker noise on the reading.

4. Use the transformer power supply circuit shown in the figure below for allowable load shorted time measurement and output noise voltage measurement.

5. Design applications so that the minus pre-V

CC

line (pin 17) is at the lowest potential at all times.

6. A limiting resistor that assures that the maximum operating current flowing into the standby pin (pin 23) does not exceed the maximum rating must be included in application circuits. This IC operates when a voltage higher than V

BE

(about 0.6 V) is applied to the standby pin.

Thermal Design Example

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

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

Pd × θc-a + Ta < 125°C ... (1) Ta: Guaranteed ambient temperature for the end product.

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

Pd × θc-a + Pd/N × θj-c + Ta < 150°C ... (2) N: Number of power transistors θj-c: Thermal resistance per power transistor

We take the power dissipation in the power transistors to be Pd evenly distributed across those N power transistors. If we solve for θc-a in equations (1) and (2), we get the following inequalities.

θc-a < (125 – Ta)/Pd ... (1)’ θc-a < (150 – Ta)/Pd – θj-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 obtain the required heat sink thermal resistance from inequalities

(1)’ and (2)’.

• Supply voltage: V

CC

• Load resistance: R

L

• Guaranteed ambient temperature: Ta

Example: Assume that the IC supply voltage, VCC, is ±26 V, RLis 6 Ω, and that the signal is a continuous sine wave. In this case,

from the Pd – POcharacteristics, the maximum power will be 134 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 in

this manner. (Note that depending on the particular safety standard used, a value somewhat different from the value of 1/8 used here may be used.)

That is:

Pd = 85 W (when 1/8 POmax is 3.1 W)

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

From inequality (1)’: θc-a < (125 – 50)/85

< 0.88

From inequality (2)’: θc-a < (150 – 50)/85 – 3.6/12

< 0.87 Therefore, the thermal resistance that satisfies both these expressions at the same time is 0.87°C/W. Note that this thermal design example assumes the use of a constant-voltage power supply, and is only provided as an

example for reference purposes. Thermal designs must be tested in an actual end product.

Overview

The STK403-400 series products are audio power amplifier hybrid ICs that consist of optimally-designed discrete component power amplifier circuits that have been miniaturized using SANYO’s unique insulated metal substrate technology (IMST). The adoption of a newlydeveloped low thermal resistance substrate allows this product to integrate six power amplifier channels in a single compact package. The adoption of a standby circuit in this device allows it to reduce impulse noise significantly as compared to earlier Sanyo products, in particular, the STK402-*00 series products.

Features

• Series of pin compatible power amplifiers ranging from 30 W/ch to 45 W/ch (10%/1 kHz) devices. The same printed circuit board can be used depending on the output power grade.

• Miniature packages — 78.0 mm × 32.0 mm × 9.0 mm *

*: Not including the pins.

• Output load impedance: RL= 6 Ω

• Allowable load shorted time: 0.3 seconds

• Supports the use of standby and muting circuits.

Series Organization

Specifications

Maximum Ratings at Ta = 25°C

These products are organized as a series based on their output capacity.

Operating Characteristics at Tc = 25°C, RL= 6 Ω (noninductive load), Rg = 600 Ω, VG = 30 dB

Notes: 1. 1ch drive

2. Unless otherwise noted, use a constant-voltage supply for the power supply used during inspection.

3. The output noise voltage values shown are peak values read with a VTVM. However, an AC stabilized (50 Hz) power supply should be used to minimize the influence of AC primary side flicker noise on the reading.

4. Use the transformer power supply circuit shown in the figure below for allowable load shorted time measurement and output noise voltage measurement.

5. Design applications so that the minus pre-V

CC

line (pin 17) is at the lowest potential at all times.

6. A limiting resistor that assures that the maximum operating current flowing into the standby pin (pin 23) does not exceed the maximum rating must be included in application circuits. This IC operates when a voltage higher than V

BE

(about 0.6 V) is applied to the standby pin.
