Hi Hsu Cheng,

Thanks for your interest in TI. Yes, you can use UCC28056 and UCC28780 as a front end transition mode PFC feeding a downstream active clamp flyback.

Is there a reference design that can provide a reference?

Hi Hsu Cheng,

It does not look like we have a reference design showcasing both UCC28056 and UCC28780 unfortunately. I would suggest using the UCC28056 and UCC28780 design calculators to determine appropriate component parameters.-. The output of the UCC28056 boost stage would be the input to the UCC28780 active clamp flyback. You can find the UCC28056 design calculator here:www.ti.com/.../toolssoftware

and the UCC28780 calculator here:www.ti.com/.../toolssoftware
