Abstract

A dual-stage boost converter is disclosed. The boost converter includes a charge pump and a boost stage. The charge pump is coupled between an input voltage source and the boost stage. The charge pump is coupled to receive the input voltage and configured to generate an intermediate voltage that is greater than the input voltage received from the input voltage source. The boost stage includes an inductor coupled to receive the intermediate voltage and is configured to generate an output voltage that is greater than or equal to the intermediate voltage.
