Abstract
A multiplexing power converter for use with a single inductor for providing multiple power outputs is disclosed. The multiplexing power converter includes first switching means for providing a first low resistance path for current to flow from a power source through an inductor so as to energize the inductor, and at least one second switching means for providing at least one second low resistance path for current to flow from the inductor so as to deenergize the inductor and provide an output current. Only one low resistance current path is provided at any one time.
