WEBENCH® Tools/UCC28070: multiple phase interleave PFC

Part Number: UCC28070

Tool/software: WEBENCH® Design Tools

Hi! Ti E2E support,

My current company used UCC28070 as two phase interleave control for 800W PFC. I would like to ask TI whether TI has another controller which can have three interleave control for over 1000W PFC ( three phase more than two phase) in order to extend the current design into 1000W output power at least. (AC side input still is single phase)

In addition, I would like to know

1. whether new IC has  boost "diode" control function or says if I use a MOSFET in replace the boost diode, the IC can run the FET (on high side).

2. Whether TI has controlled AC-DC rectifiers which basically using MOSFETs replace the rectified diodes in order to improve the system efficiency.

Looking to forwarding to your solutions!

Thanks,

Johnson Pi
