I have made another driver board for i-SMPS.
This time it is based on UCC25600. Just take a look, a few components only, and you have :
-very very low standby current (startup from the resistor !!), no extra transformer required
-very powerfull driver IR2110
-soft start
-two stage over current protection
-very easy DT adjustment (no problems with max duty as with SG3525 anymore, you can adjust it to 49% if you wish to do)
-no current sense transformer required, simple reactive divider only
-standard and LLC SMPS capability at the same board (only two capacitors change with wima MKP10 series and wind the integrated trafo)

board 28mm x 38mm
I will post some further work later on.

I am waiting.....
I have unfinished regulated smps with L6599 and I have 2pcs UCC25600 and some IR2110 in hand and I have draw schematic for it, but unfortunately i don't have time to continue
I'm glad you're making smps using ucc25600 so i can learn from you and maybe we can discuss it
