Abstract
A power controller for an electrical load is disclosed. The power controller includes a power stage operable to selectively provide an output voltage to the load. An input voltage generator supplies an input voltage to the power stage. A hysteretic comparator is operable to compare a reference voltage to a feedback output voltage from the load, the feedback output voltage being at least a portion of the output voltage, and provide a hysteretic comparator output to the power stage which controls the output voltage. A synthesizing circuit is operable to generate a synthesized voltage and couple the synthesized voltage with the feedback output voltage before the feedback output voltage is compared with the reference voltage by the hysteretic comparator. Coupling of the synthesized voltage with the feedback output voltage synchronizes the hysteretic comparator output with the input voltage provided to the power stage.
