Hi, I haven't been able to find information about Class D feedback. If anyone can provide any information I'll be very gratefull. Thanks!

Class d feedback and be pre filter or post filter.

The feedback is important because in some class d amps it forms part of the oscillator circuit.

Ok, but I need more information, how to calculate feedback, equivalent circuits, etc

It depends on the toplogy you are using.

And in some designed, like icepower, they take feedback BOTH pre and post filter....

What do you know about feedback generally? Only a few things are special in connection with ClassD.
