<P>PROBLEM TO BE SOLVED: To provide a DC-DC converter capable of increasing power efficiency under a light load. <P>SOLUTION: The DC-DC converter of synchronous rectification type is configured so that a control circuit switches a switching element on the basis of a signal with a pulse duration corresponding to a load current or a preset minimum pulse duration whichever is longer, when a reverse flow is detected. <P>COPYRIGHT: (C)2013,JPO&INPIT |
