The post 2 x 100W Stereo Power Amplifier with STK4231II first appeared on Electronic Schematic Diagram.]]> Here is the?2 x 100W stereo power amplifier with STK4231II as the main amplifier component. This is a high power audio amplifier with dual output channel at 100W max for each channel. I think it is a very good amplifier because it has capability to deliver high stereo output power with only use a single chip power IC.

2 x 100W Power Amplifier with STK4231II circuit diagram

Circuit Notes:

  • This circuit using dual polarity power supply, please see the IC datasheet for the recommended power supply voltage.
  • Mount the power IC on heatsink to prevent overheating on its.

Dual Polarity Power Supply Scheme Diagram:

Symmetrical Dual Polarity Power Supply Circuit

Use 5A center tap transformer for maximum result. Change the capacitor with higher value (about 6800uf). Maximum voltage for the circuit is 75V, recommended voltage 51V.

STK4201II Features:

  • The STK4201II series (STK4231II) and STK4201V series (high-grade type) are pin-compatible in the output range of 60W to 100W. Once the PCB pattern is designed, you can easily satisfy the requirements for new sets simply by changing the IC.
  • Built-in muting circuit to cut off various kinds of pop noise
  • Greatly reduced heat sink due to case temperature 125?C guaranteed
  • Excellent cost performance
