Hi TI guys:

I used UCC28056+UCC256304 in my 240W charger,

i have a question as below:

if I put the UCC256304 FB PIN to low by Opto, What is the RVCC status? the PFC/LLC can work normally? THX

Hi Jack,

Thanks for your interest in UCC256304. If FB pin is held low, RVCC should eventually disable.

Best Regards,
