Identify Pinout Configuration

: Refer to the datasheet to locate input pins, output terminals, and power supply rails. For STK series modules, Pin 1 is typically marked with a dot or notch. STK413-430 The is a 2-channel audio power amplifier

Configuration:

The STK413-430 is part of a pin-compatible series, meaning you can often swap it with other modules in the family to adjust power ratings without redesigning the PCB. 2-channel (stereo) AF power amplifier. Max Supply Voltage: Thermal Resistance: 3.0∘C/W3.0 raised to the composed with power C/W A center-tapped transformer connects to a bridge rectifier

| Pin | Name | Description | |-----|-------------|---------------------------------| | 1 | +Vcc (R) | Right channel positive supply | | 2 | Out (R) | Right channel output | | 3 | GND (R) | Right ground | | 4 | -Vcc (R) | Right negative supply | | 5 | Bootstrap R | Bootstrap capacitor for right | | 6 | NF (R) | Negative feedback right | | 7 | Input R | Right channel signal input | | 8 | GND (signal)| Signal ground | | 9 | Input L | Left channel signal input | | 10 | NF (L) | Negative feedback left | | 11 | Bootstrap L | Bootstrap capacitor left | | 12 | -Vcc (L) | Left negative supply | | 13 | GND (L) | Left power ground | | 14 | Out (L) | Left channel output | | 15 | +Vcc (L) | Left positive supply |

pin-compatible

These are all . However, the power supply voltage must be adjusted accordingly. For example, an STK417-430 requires ±42V, which would destroy an STK413-430.

  • A center-tapped transformer connects to a bridge rectifier and two large filter capacitors (e.g., 4700µF/50V) to create a Symmetrical Voltage (+V, 0V, -V).
  • Pin 13 connects to the Positive Rail (+V).
  • Pin 10 connects to the Negative Rail (-V).
  • Pin 8 connects to the Central Ground (0V).
