Abstract
A method of regulating voltage with a switching regulator is disclosed. The method includes sensing an output voltage provided by the regulator. If the output voltage drops below a low voltage threshold, a burst of one or more current pulses is provided. If the output voltage raises above a high voltage threshold during the burst, discontinuing the burst of current pulses. The method includes counting a number of the one or more current pulses in the burst, and comparing the number of the one or more current pulses with at least one pulse threshold. The upper current threshold is adjusted based on the number of the one or more current pulses.
