摘要： A charge pump includes a switching circuit which is interposed among first and second output capacitors, a flying capacitor, and an input power supply; and a control unit which controls the switching circuit. The charge pump is operated in an operation mode including a high-voltage outputting mode, a low-voltage outputting mode, and a relay mode. The control unit controls the switching circuit so that respective charging voltages of the first and second capacitors that are charged in the high-voltage outputting mode are gradually lowered. The control unit changes the operation mode of the charge pump by relay transition from the high-voltage outputting mode through the relay mode to the low-voltage outputting mode when a voltage lower command is given during a period when the operation mode of the charge pump is in the high-voltage outputting mode.
