Abstract
A switched-capacitor circuit for use in a high-efficiency power subsystem is disclosed. The switched-capacitor circuit includes a resonant circuit and multiple switches that couple the resonant circuit between an input power supply node and an output node to generate a voltage on the output node that is less than the voltage of the input power supply node. A sense circuit measures the current flowing through the resonant circuit and a control circuit opens and closes different ones of the multiple switches in response to a determination that the current flowing through the resonant circuit is less than a threshold value.
