Abstract
A first control switch is connected between a first terminal to which one terminal of a first boosting capacitor element is connected and a supply node of an input voltage. A second control switch is connected between a second terminal to which the other terminal of the first boosting capacitor element is connected and the supply node of the input voltage. A first switch element is connected between a third terminal to which one terminal of a second boosting capacitor element is connected and at which an output voltage is generated and the first terminal. A second switch element is connected between a node of a reference voltage side of the input voltage and the second terminal. A control circuit detects the output voltage and controls the first and second control switches to obtain the desired output voltage on the basis of a detection result.
