Abstract
A DC-DC converter includes a plurality of switches configured to be in a first charging mode until current through an inductor reaches a first current threshold to thereby indicate an end of the first charging mode. Responsive to the end of the first charging mode the DC-DC converter is configured to operate in a second charging mode for a time period ΔT in which a first side of the inductor is coupled to an input voltage and a second side of the inductor is coupled to a load. Responsive to the end of the time period ΔT, the DC-DC converter operates in a discharge mode until current through the inductor reaches its minimum.
