ABSTRACT:
A correction circuit for use in a switched power supply wherein the correction circuit provides a correction signal indicating a duty cycle adjustment necessary to modify pulse width modulation of the power supply such that the output inductor current matches the load current drawn by a load connected to the power supply. The correction circuit may be used in conjunction with feed forward and/or feed back control circuits. The correction circuit may be implemented using either digital or analog circuit components.
