Other Parts Discussed in Thread: UCC28950 , UCC28070 , UCC3895 , TEST Hello, I am currently using UCC28950 doing a 2KW prototype, with constant voltage constant current output (share the same loop with a diode OR gate), synchronous rectification EF useless…
I am also triing to make a 3kW PFC starting from PMP4259.
I have the files you need. I can send to you, just ask
Have you any chance of getting your PFC working. I have trouble myself so if you have one working could you send me the design
