Abstract
A DC/DC converter includes an input terminal for receiving an input voltage; an output terminal for providing an output voltage; a ground terminal for providing a reference voltage; a plurality of charge pump capacitors including at least a first charge pump capacitor, a second charge pump capacitor, and a third charge pump capacitor; and a switch circuit. The switch circuit includes a plurality of switches configured to allow the plurality of charge pump capacitors connected in a hybrid parallel-series arrangement between the input terminal and the ground terminal or between the input terminal and the output terminal by selectively conducting a specified portion of the switches.
