ABSTRACT:
A duty cycle estimator for determining a nominal duty cycle of an output regulator. The duty cycle estimator having at least two modes and including at least a mode one estimator and a mode two estimator. The mode one estimator to determine the nominal duty cycle as a function of prior duty cycles. The mode two estimator to determine the nominal duty cycle as a function of accumulated error. A mode selector, based on a mode selection criteria, to select a one of the at least two modes to generate the nominal duty cycle.
