Abstract
A structure and method is provided for DC to DC conversion using switched-capacitors. The DC-DC converter uses an optimized configuration of capacitors and switches that maximize the number of attainable ideal conversion ratios for the given number of capacitors. A method is provided for controlling the converter, wherein the control circuitry generates a multiphase switching sequence which turns the switches on and off in a cyclical manner. Sample switching sequences are provided to generate a set of attainable ideal conversion ratios, for up to three floating capacitors. The converter is programmable, modular and capable of dynamically varying its ideal conversion gain. It can be used to both step-up and step-down the input voltage.
