Abstract
A three-stage switched capacitor DC-DC converter capable of generating an output boosted voltage in increments of less than power supply voltage. A first stage of the DC-DC converter comprises two capacitors and three switches, which alternate a connection of the two capacitors. The two capacitors are connected in series when charging by turning one of the switches ON, and are connected in parallel when discharging by turning the other two of the switches ON.
