First question asked Welcome!

Hello. 

I'm developing a new power supply with  ICE2QS03G, but I need two secondary outputs both isolated from each other and from the primary. However, I don't find any application note for this case, so I have some questions:

Is it possible to design this topology?

Are there any application notes for it?

Is it possible to maintain cross-regulation betewen secondary windings?

I appreciate any help.

Hi,

Yes, it is possible to design.  Pls, find the design guide for ICE5QSBG.

ICE5 series is an updated version of the ICE2QS series. 

In the design guide, both output are derived from the same winding. to maintain cross regulations. 

If you need both outputs isolated then cross-regulation is difficult. since only one output is used to maintain regulation.

Best Regards,
