Abstract

A driving device is provided with: a power circuit in which it is possible to modify an output current value of an output terminal configured to have a load connected thereto; an output capacitor connected between the output terminal of the power circuit and a reference potential node; a switching element connected between the output terminal of the power circuit and the reference potential node; and a control unit that controls the output current value of the power circuit. The control unit turns the switching element ON and OFF and controls the output current value of the power circuit during a period in which the switching element is ON such that the voltage of the output terminal of the power circuit during this period is equal to or lower than the voltage applied to the load during a period when this load is OFF.
