Hi, Sean

I did not find reference design for such higher AC input. Here is my comment:

1. PFC:UCC28180. the output voltage of PFC is 800V.

2. LLC:UCC25600. Convert 800V to 400V.

3. UCC28C43: As auxiliary power controller.

Regards,

Yunsheng

Hi, Sean

UCC29910 also can support such spec. Refer to below EVM.

Using UCC29910, auxiliary power is also needed.
