Hi Wen,

I am not aware of a reference design for this high of input voltages but I will ask some AEs to respond if they have any knowledge to point your way to help.

Hi, Wen

You should keep output voltage is higher than peak input voltage to cover PF, since UCC28810&UCC28063 is boost controller.

What is your target PF?

Hi, Yung

PF of 0.95 for UCC28810 or UCC28063 is much critical. I recommend you to select UCC28180, which can achieve high PF at CCM.

For reference circuit, you can refer to below UCC28180EVM user guide.
