Question Hi freq class D amp design ideas

Hello,

I have been tasked with desiging a class D amplifier for my senior project before I graduate that is capable of going from 50Hz - 50Khz. I have encountered the difficulty of not finding a text that would aid me in the design process.
Can anyone on here recommend any resource that would aid me in designing and where I could possibly get schematics that I could review from. Thanks.

International Rectifier has extensive app notes and tutorials as well as reference designs.

Also, search this site for tons of useful info.

What is the desired output power and load impedance? There are already class d audio amplifiers out there capable of doing this. Is this going to be an amplifier for an ultrasonic application?

Would you like that on 2 layer or 4 layer? First post, "I need to download my senior term project so I can graduate", and you can't find anything because you never looked. Dartmouth huh?

What load? What a load. What a moral suck hole.. subjectively.

Hello Carvinguy,

Thanks for the link, I find it very helpful. That's exactly the kind of resource I was looking for, I had no luck with the books I got from the library, with that I should be all set. Thanks a lot again.

Hello bwaslo,

Thank you very much, for the Philips data sheet link. That's pretty much what I need to do. Thank's again for the link.
