Zusammenfassung:	PROBLEM TO BE SOLVED: To make the output voltage agree correctly with a target voltage in a DC-DC converter even under no-load or light load. SOLUTION: In the DC-DC converter 100 comprising an inductor 101, a main switching element 103 for switching storage and discharge of energy in the inductor 101, and a main switch control circuit 102 outputting a control signal VG1 for switching the main switching element 103 between on state and off state, a mute control circuit 109 switches on state and off state of a mute circuit 110 depending on the control signal VG1 and absorbs a leak current flowing from a sub-switch element 107 to an output terminal.
