<p>In a non-insulated DC-DC converter for performing direct-current power conversion by operating a first MOS transistor (11) and a second MOS transistor (12) in mutually inverted phases, the second MOS transistor (12) is held off during soft-start control. In soft-start control, the on-duty period of the first MOS transistor (11) is short immediately after the switch-on of a power source (4), and is gradually extended afterwards. <IMAGE></p> |
