摘要: Provided is a charge pump booster circuit capable of outputting desired boosted voltage that is not limited to an integral multiple of input voltage and further outputting stable boosted voltage even if a load fluctuates. In the charge pump booster circuit, gate voltage of a transistor for pumping is controlled according to voltage, which is a feedback of boosted voltage, to control the boosted voltage.
