Abstract

A charge pump circuit includes a voltage controlled oscillator. The voltage controlled oscillator operates at a lower frequency during a warm-up mode, and operates at a higher frequency during a loading mode. The lower frequency operation during the warm-up mode reduces power supply current requirements.
