Hello,

That is a 300 W EVM and a single phase should be able to handle 150 W.

Hi Mike,

Customer want to turn off one phase and use this chip in a one phase mode. Can this chip run on this mode? Thanks.

Hello,

I think is would be more cost effective to use the ucc28056 for constant on time control PFC for single phase design. The following link will get you to the data sheet.
