Abstract
A DC to DC converter includes a switching circuit and a controller. The switching circuit includes an inductor coupled to first and second voltage supply nodes and to a plurality of output loads. The controller is configured to monitor a current through the inductor and to selectively couple the inductor to each of the plurality of output loads such that at least one of the following criteria is met: 1) an average current through the inductor is minimized for the particular output loads coupled to the switching circuit, or 2) minimize a number of times the switching circuit is switched during a charging period for the particular output loads coupled to the switching circuit.
