Pin Function
Description
1 VCC Positive input supply voltage.This pin is connected to an external capacitor for energy storage.The startup circuit sources current out of this pin to initially charge the capacitor.When the voltage reaches the upper threshold limit of the undervoltage lockout circuit, the startup circuit will turn off, and the power supply will begin operation.Power is then supplied to the chip via this pin, by virtue of the auxiliary winding.2 Feedback Input The error si
