ABSTRACT:
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.
