Abstract
A method of operating a buck converter is disclosed. The buck converter includes a first capacitor, a second capacitor, and an inductor between a node and an output of the buck converter. The method includes, during a first portion of a cycle, coupling the first capacitor and the second capacitor in series between an input of the buck converter and a ground, wherein the first capacitor is coupled between the input of the buck converter and the node, and the second capacitor is coupled between the node and the ground. The method also includes, during a second portion of the cycle, coupling the second capacitor and the first capacitor in series between the input of the buck converter and the ground, wherein the second capacitor is coupled between the input of the buck converter and the node, and the first capacitor is coupled between the node and the ground.
