Part Number:UCC28070A
My PFC system needs external overcurrent detection output.
In order to implement it with UCC28070A, I'm going to make PKLMT voltage very large, and tie external overcurrent detector output to PFC Enable (See 7.3.13 on the datasheet).
One of the concerns of this method is propagation delay of the over current protection will be larger.
Could you please tell me what will happen when propagation delay is large?
How long delay will be tolerable for the PFC?
Best regards,
Kazuki
