Hi all,

Does UCC28070 active clamp flyback keep the high cross regulation with multiple output channels?

Is there a way to get as good cross regulation as LLC?

To achieve good cross regulation with UCC28780 we recommend you follow the design techniques described in this video training.ti.com/multiple-output-flybacks-how-improve-cross-regulation

We do not have any reference design at this moment that demonstrates performance of UCC28780 with multiple outputs.

Best Regards,
Eric
