Tool/software:
Hi team,
I've checked UCC28180 and have some questions regarding to the switching frequency.
Customer want to use less PCB area for PFC, so they want to use higher frequency like 250kHz as specified in the datasheet.
But when I check the WEBENCH the user preference freq is limited 180kHz not 250kHz.
Is there any concern or issue if we use 250kHz as switching frequency for UCC28180?
If so, then what is the maximum Fsw and Inductance for boost PFC with below condition?
- AC 110~220V (85~265V)
- DC 380V 450W output
- ~250kHz Fsw
Bests,
Ernest Cho
