Hi everyone,
I am working on a Class-D audio amp for a design project. It takes an analogue input and uses no fancy custom IC's. I can't find much on this site about class-d - am i looking in the wrong place or what? I would have though someone would have done this before. I am using an LM566 to generate a triangle wave, a comparator, some lockout logic, some mosfet driver chips (such as the MAX626) and a power mosfet h-bridge. The switching frequecny will be about 100kHz or maybe less (its only for a subwoofer) and the total power to load will be 50-100W rms. Any one have any suggestions, comments, etc.
Cheers, hugo_nz
