    Hello,

    The OVP pin of this device is actually is use for ZCS detection as well as OVP.   I would not recommend using this pin to shut down the UCC28600.

    If you want to power down the UCC28600, I would recommend using a series pass regulator using an NPN transistor and resistors to pass and regulate voltage to VDD.  To turn-off the device you would then use a logic level FET to pull down on the NPN transistor to disable the UCC28600.  Please refer to the schematic below for details.
