ABSTRACT:
Provided is a DC-DC converter circuit which is stably operated without being affected by a size of an output capacitor (111) and a cost thereof. When a switching element is turned on so that a charge current that was flowing into an output capacitor flows into the switching element, the current is converted into a voltage to be added to an output voltage, and a resultant voltage is fed back to a control system.
