UCC28056: supply voltage for PFC UCC28056

Part Number: UCC28056
Other Parts Discussed in Thread: UCC28740,

Hi team,

Right now we use PFC controller and Flyback (UCC28740 and 28056 ) as the power supply solution.

So what is the recommended supply voltage for PFC UCC28056?  Can UCC28056 use the same Vs as UCC28740 (That will decide whether the UCC28740 customized transformer auxiliary winding can supply both)

 

Thanks

Lillian
