Hi,

Is it possible to design AC-DC input from 60V - 600V using UCC28722?

Dear Yash,

Thanks for interested in TI's solution.
The UCC28722 is for driving BJT switch, just want to make sure you choose the suitable controller.
The maximum input range I can find is around 85-528 in our database.
Is this okay for your design?

Can you also provide your output power and output voltage?
I can help on searching the suitable design for you.

Best Regards
Kevin

HI,

AC:
VIn Min: 60V Max: 650V

DC:
Vout - 12V @ 50 ma , 3.3V @120 ma

Kindly advise for suitable design.

Also advise if we can do modification in SLUA721.

Dear Yash,

I try to find the database, but we don't have similar specification.
The SLUA721 should work well if you want to modify it.

Best Regards
Kevin
