摘要：
A step-up switching voltage regulator includes two or more inductors and a switching network. A control circuit drives the switching network in a repeating sequence that includes: a magnetizing phase where the inductors are connected in series between an input voltage and ground; and a charge transfer phase where the inductors are connected in parallel to provide current to an output node with at least one of the inductors is connected between ground and the output node.
