Hello Hirotsugu,
There are no reference designs for the UCC28056 at such a low power level.
I'm wondering if this is for an LED application? If so, one of TI's PFC controllers designed specifically for the LED market may be more suitable.
TI has…
Hi Kaji,
The UCC28810 might be able to work. Page 16 of the datasheet shows how this can work as a PFC flyback, but you can adjust it for the lower input voltage.
I hope this answers your question.
