[Remarks] *1: For 1-channel operation *2: Unless otherwise specified, use a constant-voltage power supply to supply power when inspections are carried out. *3: The output noise voltage values shown are peak values read with a VTVM. However, an AC stabilized (50Hz) 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 and output noise voltage measurement. *5: The impression voltage of ‘#13 (Stand-By) pin’ must not exceed the maximum rating. Power amplifier operate by impressing voltage +2.5 to +5.5V to ‘#13 (Stand-By) pin’. *6: Please connect -PreVCC pin (#1 pin)with the stable minimum voltage, and connect so that current does not flow in by reverse bias. *7: Thermal design must be implemented based on the conditions under which the customer’s end products are expected to operate on the market. *8: The case of this Hybrid-IC is using thermosetting silicon adhesive (TSE322SX). *9: Weight of HIC: 24.8g Outer carton dimensions (W×L×H): 452mm×325mm×192mm

[Thermal Design Example for STK433-290-E (RL = 6Ω)] The thermal resistance, θc-a, of the heat sink for total power dissipation, Pd, within the hybrid IC is determined as follows. Condition 1: The hybrid 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 θj-c: Thermal resistance per power transistor However, the power dissipation, Pd, for the power transistors shall be allocated equally among the number of power transistors. The following inequalities result 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 VCC • Load resistance RL • Guaranteed ambient temperature Ta
No. A1630-8/13
STK433-290-E [Example] When the IC supply voltage, VCC, is ±33V and RL is 6Ω, the total power dissipation, Pd, within the hybrid IC, will be a maximum of 109.7W at 1kHz for a continuous sine wave signal according to the Pd-PO characteristics. For the music signals normally handled by audio amplifiers, a value of 1/8PO max is generally used for Pd as an estimate of the power dissipation based on the type of continuous signal. (Note that the factor used may differ depending on the safety standard used.) This is: Pd ≈ 85.0W
(when 1/8PO max. = 10W, PO max. = 80W).
The number of power transistors in audio amplifier block of these hybrid ICs, N, is 6, and the thermal resistance per transistor, θj-c, is 2.1°C/W. Therefore, the required heat sink thermal resistance for a guaranteed ambient temperature, Ta, of 50°C will be as follows. From formula (1)' θc-a < (125 − 50)/85.0 < 0.88 From formula (2)' θc-a < (150 − 50)/85.0 − 2.1/6 < 0.82 Therefore, the value of 0.82°C/W, which satisfies both of these formulae, is the required thermal resistance of the heat sink. 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 ’s end product.

Concerning pin 13 reference voltage VST <1> Operation Mode The switching transistor in the bias circuit turns on and places the amplifier into the operating mode when the voltage flowing into pin 13 (VST) becomes 0.25V or greater. <2> Stand-By Mode When the voltage flowing into pin 13 (VST) is stopped (=0V), the switching transistor in the bias circuit turns off, placing the amplifier into the standby mode. (*1) The current limiting resistor (R1) must be used to ensure that the voltage flowing into the stand-by pin (pin 13) does not exceed its maximum rated value VST max. (*2) The pop noise level when the power is turned on can be reduced by setting the time constant with a capacitor in operating mode. (*3) Determines the time constant at which the capacitor (*2) is discharged in standby mode. 2) Load short detection block Since the voltage between point B and point C is less than 0.6V in normal operation mode (VBE < 0.6V) and TR1 (or TR2) is not activated, the load short-circuit detection block does not operate. When a load short-circuit occurs, however, the voltage between point B and point C becomes larger than 0.6V, causing TR1 (or TR2) to turn on (VBE > 0.6V), and current I2 to flows 3) Latch-up circuit block When I2 was supplied to latch-up circuit, TR3 operate. VST becomes Stand-By Mode (0V) when TR3 operates (I3 flows), the power amplifier is protected. Stand-By Mode is maintained when once TR3 operates because TR3 and TR4 compose the thyristor. It is necessary to make the Stand-By Control voltage (*2) L (0V) once to release Stand-By mode and to make the power amplifier operate again. After, when Stand-By Control (*2) is returned to H (ex, +5V), it operates again. (*4) I3 is changed depending on the power-supply voltage (-VCC). Please set resistance (R2) to become I1 < I3 by the following calculation types. I1 ≤ I3 = VCC/R2 4) DC offset protection block The DC offset protection circuit is activated when ±0.5V (typ) voltage is applied to either "OUT CH1" or "OUT CH2," or "OUT CH3," and the hybrid IC is shut down (standby mode). To release the IC from the standby mode and reactivate the power amplifier, it is necessary to set the standby control voltage temporarily low (0V). Subsequently, when the standby control is returned to high (+5V, for example), the power amplifier will become active again. The protection level must be set using the 82kΩ resistor. Furthermore, the time constant must be determined using 22μ//22μ capacitors to prevent the amplifier from malfunctioning due to the audio signal.

[Thermal Design Example for STK433-290-E (RL = 6Ω)] The thermal resistance, θc-a, of the heat sink for total power dissipation, Pd, within the hybrid IC is determined as follows. Condition 1: The hybrid 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 θj-c: Thermal resistance per power transistor However, the power dissipation, Pd, for the power transistors shall be allocated equally among the number of power transistors. The following inequalities result 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 VCC • Load resistance RL • Guaranteed ambient temperature Ta
No. A1630-8/13
STK433-290-E [Example] When the IC supply voltage, VCC, is ±33V and RL is 6Ω, the total power dissipation, Pd, within the hybrid IC, will be a maximum of 109.7W at 1kHz for a continuous sine wave signal according to the Pd-PO characteristics. For the music signals normally handled by audio amplifiers, a value of 1/8PO max is generally used for Pd as an estimate of the power dissipation based on the type of continuous signal. (Note that the factor used may differ depending on the safety standard used.) This is: Pd ≈ 85.0W
(when 1/8PO max. = 10W, PO max. = 80W).
The number of power transistors in audio amplifier block of these hybrid ICs, N, is 6, and the thermal resistance per transistor, θj-c, is 2.1°C/W. Therefore, the required heat sink thermal resistance for a guaranteed ambient temperature, Ta, of 50°C will be as follows. From formula (1)' θc-a < (125 − 50)/85.0 < 0.88 From formula (2)' θc-a < (150 − 50)/85.0 − 2.1/6 < 0.82 Therefore, the value of 0.82°C/W, which satisfies both of these formulae, is the required thermal resistance of the heat sink. 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 ’s end product.

Concerning pin 13 reference voltage VST <1> Operation Mode The switching transistor in the bias circuit turns on and places the amplifier into the operating mode when the voltage flowing into pin 13 (VST) becomes 0.25V or greater. <2> Stand-By Mode When the voltage flowing into pin 13 (VST) is stopped (=0V), the switching transistor in the bias circuit turns off, placing the amplifier into the standby mode. (*1) The current limiting resistor (R1) must be used to ensure that the voltage flowing into the stand-by pin (pin 13) does not exceed its maximum rated value VST max. (*2) The pop noise level when the power is turned on can be reduced by setting the time constant with a capacitor in operating mode. (*3) Determines the time constant at which the capacitor (*2) is discharged in standby mode. 2) Load short detection block Since the voltage between point B and point C is less than 0.6V in normal operation mode (VBE < 0.6V) and TR1 (or TR2) is not activated, the load short-circuit detection block does not operate. When a load short-circuit occurs, however, the voltage between point B and point C becomes larger than 0.6V, causing TR1 (or TR2) to turn on (VBE > 0.6V), and current I2 to flows 3) Latch-up circuit block When I2 was supplied to latch-up circuit, TR3 operate. VST becomes Stand-By Mode (0V) when TR3 operates (I3 flows), the power amplifier is protected. Stand-By Mode is maintained when once TR3 operates because TR3 and TR4 compose the thyristor. It is necessary to make the Stand-By Control voltage (*2) L (0V) once to release Stand-By mode and to make the power amplifier operate again. After, when Stand-By Control (*2) is returned to H (ex, +5V), it operates again. (*4) I3 is changed depending on the power-supply voltage (-VCC). Please set resistance (R2) to become I1 < I3 by the following calculation types. I1 ≤ I3 = VCC/R2 4) DC offset protection block The DC offset protection circuit is activated when ±0.5V (typ) voltage is applied to either "OUT CH1" or "OUT CH2," or "OUT CH3," and the hybrid IC is shut down (standby mode). To release the IC from the standby mode and reactivate the power amplifier, it is necessary to set the standby control voltage temporarily low (0V). Subsequently, when the standby control is returned to high (+5V, for example), the power amplifier will become active again. The protection level must be set using the 82kΩ resistor. Furthermore, the time constant must be determined using 22μ//22μ capacitors to prevent the amplifier from malfunctioning due to the audio signal.
