Mini Class-D Amplifier PCB Layout

Elcircuit will share the PCB layout but not from us, so whether this amplifier works or not is still 50:50 but the actual schematic is working well. The circuit scheme was designed by Mr. Kartino Surodipo, this amplifier circuit is quite simple, using the LM311 IC as a comparator, and the level shifter uses a 2n5401 transistor, so this amplifier does not use a Logic IC like the half-bridge version of the d2k5 or d1k5 amplifier circuits.


Mini Class-D Amplifier Specifications

Uses 12VDC bias voltage
Comparator uses LM311
Gate driver uses IC IR2110/IR2113
Mosfet can use IRFP250 and IRFP4227. IRFP260, or IXYS 82N25
Easy to assemble and simple
Power output up to 750W RMS
Audio Input balance.

    Just to verify working fine for me can check on:

    I do not 31df6 or df6 so that I had used mur460 at place of it with a 10r register. Please use a speaker protection circuit some time it produce some dc voltage on output.
