I am designing LLC 300W/60V battery charger with GanFET. I am facing startup issue as VCC and RVCC is restarting after 1sec.
i have checked the previous answer available on TI forum related to UCC256304, but that does not help, still facing the same issue.
i have played around with BLK, BW, and ISNS.
BW pin is connected to ground. BLK voltage is adjusted at 75% of PFC voltage. and ISNS resistor is reduced to 47ohm and 220pF.
