Hi stewin
Pls check the below link
http://www.diyaudio.com/forums/class-d/166214-ucd-25-watts-1200-watts-using-2-mosfets-188.html

and if you need a self osc. schematic(fsw=450KHz) i will give you

 

[stewin]

are you using irfp250 and at what voltage are you using? are the fets in the photo running in paralleled or full bridge? what about the noise at very low volumes is it present?

Hi Norazmi

sir microsim,can tell me password

 

[norazmi]

The sound is i can say, irs2092 is more silent and quiet and not sensitive to other electronic devices. irs2092 is special build for audio and ir2110 is not. For example you can compare class D 200 wrms with TL074 and ucd style with LM311 + ir2110. I think you can get it . You can order irs2092 through website online such as ebay, digikey, future electronic, etc..... there is alot. Its hard to get because you must understand because of irs2092 become so popular and most of china guys making class D amp with it, so they will not sell it at cheap price because they want do business and make money. So maybe little high price at this time .

Hi stewin

my schematic shows 1x IRFP250 and my proj. Pic. shows 3x IRFP240 Parallel both you can use max +85 -85 Volt supply
i tested with +45v.....+72v only. No noise very clear sound @LOW VOLUME and COOL
in DIY everyone says IRFP240 not good for class D, my side no problem(fsw=132KHz)with paralled.you can play 20Hz to 20KHz. (tested with 12" Fullrange speaker).

 

[stewin]

what was your load and was your power supply linear or smps
