D200 Class-D Power Amplifier for DIY Audio

Power Amplifier D200 is quite good and reliable in its performance has a power output of about 200Watt 8Ohm. Power enough qualified to drive 12-inch subwoofer speakers. And also no less interesting, this power amplifier is perfect for you who just started (beginner) assemble class D power amplifier. By composing, the circuit of Op-Amp TL074 as a comparator circuit. audio signal and triangular wave then driven again by the driver transistor BD139 and BD140. And the final will be processed by the IRF9540 and IRF540 MOSFET transistor. Then the signal is still shaped square wave will be filtered by a low pass filter circuit to become a sine wave. An output will be forwarded to drive the speakers.

Below the full schematic of D200 Class-D Amplifier, simple Class-D Amplifier and suitable for a beginner of Class D Amp Fans DIY Audio.

PCB Design D200 Class D Amplifier

This Power Amplifier is more efficient than power amplifier conventional. Power supply voltage need for this amplifier about +45VDC GND -45VDC. Use the good power supply or you can use switching power supply for audio that has minimum 10A ratings.

Amplifier Project:
200w power amplifier circuit class D

Electronic Circuit is a good site for hobbyist also who would like to try DIY because it shared good circuits. If you have a personalized circuit requirement you may feel free to request it through the comment box or contact me.


What core did you use on the coil in the output filter? Send me the PCB bills. Thank you in advance!

The core i use from the Junk PSU PC. Use 22uH .

Please i want to make a kind of amp, but using two irfp460

you can use class D900 W ot this site.

I need the clearly image for D200 sir, please send to my email Thanks u very much

Please click the image and you can see the clear schematic.

Thanks for your comment.

I enjoyed reading your article :) PLease continue publishing helpful topics like this. Regards, from Let's get gadgets.

clearly image and parts list please

Click the image to view more large and clear schematic or pcb

Hello! I'm interested on this project but I see there's no PCB file or PDF, only an image. If you want I can collaborate by tracing the PCB using Sprint Layout 6 with all the benefits that mean.

Hai dear ,
please send clear image and more information of class d amplifier schematics
