Abstract: The disclosed embodiments provide an apparatus that controls a flyback converter for use with a computer system. During operation, the apparatus senses an output voltage and output current of the flyback converter. The apparatus then switches a mode for controlling the flyback converter from a discontinuous mode to a continuous mode based on the sensed output voltage and the sensed output current.

Abstract: The disclosed embodiments provide a system that facilitates operation of a power adapter in hiccup mode. The system includes a bleeding mechanism that reduces a hiccup time of the hiccup mode by increasing a leakage current of the power adapter. The system also includes an activation mechanism that activates the bleeding mechanism upon detecting a voltage drop associated with the hiccup mode.
