Switched-capacitor DC-DC converters will become more attractive for power-supply-on-chip applications if they can provide variable output voltages. This paper describes how the topology of a SC DC-DC converter can be reconfigured dynamically in order to realize this goal. We describe a three-stage converter with coarse and fine control of the output voltage.
