Hi Yogeshks1:

Is this OK for your reference? This is high performance Class-D OPAMP loop.

-B change to ground, speaker change to your load and connect to ground.

Remove input cap, it can change to high voltage input high power buck DCDC.

This is IR4301M for your reference:https://www.infineon.com/cms/en/product/power/class-d-audio-amplifier-ic/integrated-class-d-audio-am...
