I've almost completed the design of a 150W 35-60V Input and +15 / -15V Output DC-DC LLC resonant converter using L6599. On the secondary side I have a center tapped winding configured across a full bridge to deliver +15V and -15V, with the center tap as my floating GND. The rectifier diodes are consuming considerable power, rather hot. I have clearly tried schottkys but still rather hot. I could try FERD rectifiers, which will bring power dissipation down to just a couple of watts. However this is a battery powered application so power efficiency is important.
I would like to try using the SRK2000A with MOSFETs, however I don't see any applications where the controller is used with a bi-polar output.
Is it possible to configure the SRK2000A to full bridge rectify and produce +15V and -15V from a center tapped secondary?
