I am considering using LM34927 to try out flybuck topology. I want to generate 4 outputs -- 5V&10V on primary side and 5V&10V on the secondary side. In the application note and datasheet, it only mentioned about multiple outputs on the secondary side. So I am wondering if it works also to have one of the coupled output on the primary side. If so, any recommendation for the transformer? Otherwise I will have to go back to more familiar flyback design.
