Abstract
A power switch transistor for a switching power converter is maintained on during a re-startup period by a zener breakdown voltage following a fault condition for the switching power converter. A source voltage from the power switch transistor is used to charge a VCC capacitor that stores a power supply voltage for a controller for the switching power converter.
