In a non-insulated DC-DC converter for performing direct-current power conversion by operating a first MOS transistor and a second MOS transistor in mutually inverted phases, the second MOS transistor is held off during soft-start control. In soft-start control, the on-duty period of the first MOS transistor is short immediately after the switch-on of a power source, and is gradually extended afterwards.
