NCP1230 confirms that the low output power condition is present, and the internal SW1 opens, and the PFC_Vcc signal output is shuts down. While the NCP1230 is in the skip mode the FB pin will move around the 750 mV ...

... PWM controller enters the skip mode and does not enable the PFC_Vcc output. 12.6 V/ 5.6 V Ramp ON Semiconductor recommends that the Vcc capacitor be at least sure that the Vcc supply voltage does not drop below Vccmin (7.7 V typical) during standby power mode and unusual fault conditions.
