ABSTRACT:
A charge pump DC/DC converter having an improved the ripple characteristic in its output voltage and make it possible to adjust the boosting rate in a stepwise manner. In phase I, two flying capacitors Ca, Cbare connected in series between voltage input terminal12and voltage output terminal14. In this connection state, flying capacitor Cais charged by the current supplied from DC power supply10, while flying capacitor Cbdischarges to the load side. In phase II, flying capacitor Cais connected between voltage input terminal12and voltage output terminal14, while flying capacitor Cbis connected between voltage input terminal12and the ground potential. In this connection state, flying capacitor Cadischarges to the load side, while flying capacitor Cbis charged by the current supplied from DC power supply10.
