Abstract
Method and apparatus for producing an auxiliary voltage in a switching power supply. One or more auxiliary windings are coupled to the main inductor of the switching power supply. A synchronous switch is used in conjunction with the auxiliary winding to provide rectification and additionally provides waveform averaging which improves efficiency and voltage regulation over varying load conditions.
