Hi Support team

my customer would like to adopt UCC28063 in 750W application for TV

two questions

PFC choke/MOSFET would like to operate in parallel, anything need to be consideration?
Is this part supporting Master/Salve function?

1. Yes and each phase will be naturally interleaved. Please read the datasheet for its operation mechanism. Also, I suggest you to get an EVM to help study this device and the PFC based on this device.

2. No slave channels as clearly stated in the datasheet.

Hi Hung,

thanks a lot for reply,

my first question is one phase but PFC choke/MOSFET in parallel, which means it will have PFC choke/MOSFET * 4, is that works?

I think what you want to do but can you draw you circuit so I can have clear understanding what you want to do?
