Dc-dc converter and power device including the same

Abstract

The present disclosure refers to direct current-to-direct current (DC-DC) converters and power supplies including the same. In an embodiment, a DC-DC converter includes a first switching circuit, a second switching circuit, a fourth capacitor coupled to a second node, and an inductor-capacitor (LC) filter coupled to a third node. The first switching circuit includes a first transistor coupled between a first capacitor and an input node, a second transistor coupled between the first capacitor and a second capacitor, a third transistor coupled between a first node and a third capacitor, and a fourth transistor coupled between the third capacitor and a ground node. The second switching circuit includes a fifth transistor coupled between the second capacitor and the third capacitor, a sixth transistor and a seventh transistor coupled between the first capacitor and the third capacitor, and an eighth transistor coupled between the first capacitor and the ground node.
