Abstract

Circuits, methods, and system dor DC voltage conversion are disclosed. A charge pump circuit is described that includes input switches and output switches that are individually controlled by different clock signals to alternatively couple energy storage capacitors to an input and output. The individualized switching control allows for the use of clock signals with no overlapping transitions to improve conversion efficiency. The system suppresses reverse current losses efficiently.

Keywords
