Abstract
A circuit and method for regulating an internal power supply of a switching converter is presented. A switching converter with a depletion mode power switch coupled to an enhancement mode power switch via a switching node and an energy storing element coupled to the depletion mode power switch is provided. The energy storing element may be adapted to provide energy to the switching converter. For instance, the energy storing element may be a capacitor. Optionally, the switching converter may comprise an inductor coupled to the depletion mode transistor, the inductor being adapted to provide an inductor current.
