Half bridge Si824xClassD-KIT: https://www.silabs.com/documents/public/user-guides/Si824xClassD-KIT.pdf#search='si824x'
Yes I have seen it but its dual supply pre filter feedback class D but Im looking for full bridge post filter class D amplifier design. Does anyone know an expert class D designers who can do professional design services?
We design and use these Si824 chips. All my designs are POST FILTER feedback. I do not design any pre filter class D amplifiers.
The nice thing about these series of chips is the ability to dynamically vary the dead time. Keep dead time low for lower powers and drive it high when high power is demanded. Reliability is vastly improved.
It is of course no problem to deisgn either single ended or full bridge designs.
How much power and into what load impedance are you looking for?

The schematic is quite a mess,and i haven't tested it with si gate drivers,you'll have to do some more work yourself i'm afraid.It is based on ucd and works on single supply,full bridge,with post filter feedback.If you attempt it pay special attention to the feedback network,make sure you get enough signal to the comparator inputs,but not too much to latch them up.Good luck
Here is a simpler schematic that inspired me
Keep in mind that designing an amplifier takes time,an no one will do that for you,especially for free,this is why I had to learn to do it myself
