Part Number:UCC28951-Q1
Hi Experts,
On our designed PCB, there are serge on the current of primary side of transformer, we add LPF on CS pin to avoid the surge.
1. Is this understanding correct to avoid this surge?
2. If this answer is yes, what fc should we set for this LPF? We are currently set fs at 200KHz to filter this surge.
Regards,
