Abstract
A booster circuit includes a first booster unit having a first output terminal from which a boosted voltage is output. The first output terminal is connected to an external output terminal. A second booster unit has a second output terminal from which a boosted voltage is output. The second output terminal is connected to the external output terminal. A control circuit outputs a first control signal used to control the operation of the first booster unit and a second control signal used to control the operation of the second booster unit. Further, the control circuit controls the first and second control signals so that a transition between the operative state and the non-operative state of the first booster unit and a transition between the operative state and the non-operative state of the second booster unit will be made at different timings according to output voltage of the external output terminal.
