UCC39002: Please help to review schematic

Ben Kuo

Part Number: UCC39002

Dear expert,

We designed in UCC39002 for PSU application and done the schematic.

I would like to double confirm with you if there is any risk in this schematic or not. Please help to review it, thanks!

Hello Ben Kuo,
The UCC39002 has a max rating of 15V and you are applying 54V to the VDD and ADJ pins.
This will not work.
If you wish to attach the full schematic in pdf form then I review in greater detail.

Regards
John
