Abstract

A multi-phase, coupled-inductor, DC-DC voltage converter operates in discontinuous conduction mode (DCM) when the system is operated at low output power demand. An embodiment of the converter switches to operating in continuous conduction mode (CCM) when the system is operated at high output power demand. Operation in single-drive and rotating phase DCM operation at low power are described. An alternative embodiment operates in a multiple-drive, rotating-phase, discontinuous conduction mode during at least one condition of output power demand.
