发明名称 Semiconductor integrated circuit supplying voltage to a load using a charge pump and electronic device including the same
摘要 A semiconductor integrated circuit includes a charge pump boosting an input voltage and outputting the boosted voltage to a load, and a charge pump control circuit outputting a voltage to the charge pump based on the output voltage of the charge pump and determining an upper limit value of a current to be output to the charge pump based on the output voltage of the charge pump.
