Abstract

A voltage converter circuit comprises a charge pump circuit, a switching converter circuit, and a control circuit. The charge pump circuit includes multiple switch circuits connected in series. The switching converter circuit includes a first inductor coupled to an output node of the voltage converter circuit, and a second inductor coupled to a series connection of the multiple switch circuits. The control circuit is configured to control activation of the multiple switch circuits to generate a regulated voltage at the output node, and to activate each of the multiple switch circuits when a drain to source voltage of the switch circuit is zero volts.
