ABSTRACT:
An inductor6accumulates an energy therein or releases the accumulated energy according to the state of a main switch element10being turned ON/OFF. When the inductor6releases an energy, if a sub-switch element12is in the ON state, a current is passed through a circuit downstream of the sub-switch element12, thereby increasing an output voltage VO1. The sub-switch element12is a P-channel MOS transistor, and a sub-switch control circuit18outputs a control signal VCT1for the sub-switch element12. A level shift circuit19receives an output-side potential VP of the inductor6, and outputs, as a control signal VG1applied to the gate of the sub-switch element12, the potential VP if the control signal VCT1is at the L level or a potential (VP−VM) lower than the potential VP if the control signal VCT1is at the H level. Thus, the output voltage of the DC-DC converter can be made precisely equal to the target voltage.
