Abstract
An object of the present technology is to stably operate a power supply circuit. A charge switch is connected to a first terminal of a capacitor and charges the capacitor with an input voltage on the basis of a control signal inputted to a control terminal. A discharge switch is complementary with the charge switch, is connected to the first terminal of the capacitor, and discharges on the basis of the control signal inputted to the control terminal the voltage charged to the capacitor, thereby generating an output voltage. A charge control signal converting section converts a charge control signal that controls the charge into a control signal referenced to the input voltage and inputs the resulting control signal to the control terminal of the charge switch. A discharge control signal converting section converts a discharge control signal that controls the discharge into a control signal referenced to the output voltage and inputs the resulting control signal to the control terminal of the discharge switch. A pulse voltage supplying section supplies a pulse voltage to a second terminal. A control signal generating section exclusively generates the charge control signal and the discharge control signal and supplies the charge control signal and the discharge control signal.
