Abstract
A duty cycle estimator comprises an error generator that compares an output of a switching regulator to a reference to generate an output error, wherein the switching regulator operates in accordance with a switching period. An accumulator determines an accumulated error of the output error over a time period of at least N times the switching period of the switching regulator, where N is an integer. An adjustment determiner adjusts a duty cycle for the switching regulator based on the accumulated error of the output error over the time period.
