Abstract
A power supply as described herein includes a voltage converter, main controller, and a bias controller. The voltage converter including a primary stage and a secondary stage. The controller is operable to control regulation of an output voltage from the secondary stage based on a received feedback signal. As its name suggests, the output voltage from the secondary stage powers a load. During certain load conditions, the bias controller maintains (via novel biasing) a magnitude of a power supply voltage above a bias threshold value. More specifically, the bias controller is operable to prevent the power supply voltage from falling below the bias threshold value, preventing an under voltage lockout condition such that the controller is able to quickly continue conveyance of sufficient energy from the first stage to the second stage when the load increases a rate of consuming power provided by the output voltage.
