Abstract
A hybrid Direct Current (DC) to DC converter is disclosed for efficiently converting an input voltage from one level to another. In a preferred embodiment, a dual phase charge pump is combined with a buck converter and a switch controller to provide a converted voltage that is useable to cellular handset circuits based on power amplifier (PA) technology.
