Hello, at this time I will share about power amplifier class-d using IRS20957 class-d amp driver, this amplifier using half-bridge topology, mono power amplifier. Output power amplifier up-to 500W RMS at load 4 Ohm with supply voltage 90VDC. continous output power up-to 300W RMS.
In the previous post Power Amplifier Class-D IRS20957 Behringer B215D I have also made this amplifier, but the difference in the component that I use. in this post, I use the SMD component, so it looks even tinier, and this is highly recommended for power amplifier lovers with a simple and minimalist design that doesn't take up much space.
And for the PCB driver, I made it apart to make it more minimalist, and it looks cooler. besides that, the PCB with 2 layer design is also quite cheap if we order at JLCPCB because the dimensions are below 10x10cm.
The following circuit schematic for IRS20957 drivers:
