Hi,
Going to do offline flyback (UCC28C45) with all PTH. 400Vin, 60Vout, 90W. 25kHz.
Will damp the switching transition to reduce noise....will use heavy-as-poss current sense filter......still a bit worried about lead inductances though...do you think this will be OK?
Will be in DCM at 400Vin....but for short intervals at down to 340V, will be just inside CCM.
