Hi,
Could anyone recommend a PFC controller for 1kw and 480VAC line input? Any demo boards available?
Thank you!

Thank you so much!
Actually I've used UCC28810 in flyback configuration extensively, but I never think outside the box.
The UCC28180 is tempting but likely, the UCC28063A will be a better fit as downstream, I need to provide 4x250W independent DC to DC convertors to 50V/5A for an LED application ( initially considering 1PFC+ 4xLLC's).
I may use 4 x UCC28063A, I have to see if I could synchronize them.
I'll do the math and check if the parameters are realistic.
Does TI have a Mathcad app note on this UCC28063A?
Regards,
Stefan
