UCC28180: TIDA-00779

Hello dear,

I have an inquiry about the PFC ON signal for the PFC shutdown circuit in TIDA-00779. I want to know the type of this signal, voltage-current, or which signal you are used to checking the operation of the circuit??

in my circuit, I want to feedback this signal from the overvoltage and overcurrent protection of the converter. i.e in the case of the normal operation, the PFC ON signal is presented and in the case of the up normal operation, the signal PFC ON is absent. what value and type of the PFC ON should I use to implement this circuit??

thanks a lot in advance
