I have no such experience but I think you can have a try, just make sure all the voltages apply to UCC39002 are positive, that means you should take the negative rail as reference for all device functions. Thanks

Hello John san, Oliver-san,

Thank you for the reply.I understood.
For Non-Isolated DCDC, should we connect ADJ pin(S+) to FB pin of DCDC converter(TPS54560)?
