Other Parts Discussed in Thread: LM5021, UCC28730, UCC28911, UCC28C43
Hi Team,
Customer is doing a Flyback Aux Power Solution for their LLC system. They have already test UCC28740 with demo board. But the working frequency is low, and output ripple is high when I change to our design.
They want a fix-frequency flyback controller with HV pin.
- Input: 400Vin
- Output: 12V/0.3A
- Ripple:<200mV。
- Freq: 100k
Do you have any good proposal? Many thanks!
regards,
Bell
