PMP22087: UCC25640X FLYBACK TRANSFORMER INPUT SUPPLY

Part Number: PMP22087

Tool/software:

Hi everyone,

      I am currently working on an AC-to-DC converter project. I took reference from the AC/DC PSU, 240W cont. 336W peak EVM board, but I do not understand what input voltage this transformer takes from the LLC (UCC25640X). 

Refer this schimatic.

best regards.
