Is there any reference circuit for DC 96V input to 15V 1A and 5V 1A output ?

or any suggestion how to design the transformer?

Hi PYTsai,

The UCC28910 is limited to ~7.5W output power and would not be able to support a 20W design unfortunately. Would a controller + external MOSFET be acceptable for your design?

Hi Ben,

Yes, controller + external MOSFET is ok for us.

Any suggestion?

Hi PYTsai,

The closest reference design I am aware of is TIDA-01503. It will need to be modified slightly to meet your exact requirements. You can follow the design guide:http://www.ti.com/lit/ug/tidudd4a/tidudd4a.pdf.
