ABSTRACT:
A controller for, related method of controlling a switch of, a power converter and a power converter employing the same. The controller is employable with a power converter including a switch of a power train configured to conduct for a duty cycle and provide a regulated output characteristic at an output thereof. In one embodiment, the controller includes a sparse analog-to-digital converter configured to determine a difference between the output characteristic and a desired characteristic and provide an error signal representing the difference in discrete steps. A magnitude of the discrete steps is small when the difference is small and the magnitude of the discrete steps is larger when the difference is larger. The controller also includes a duty cycle processor configured to provide a digital duty cycle signal to control the duty cycle of the switch as a function of the error signal.
