<P>PROBLEM TO BE SOLVED: To provide a multiphase DC/DC converter circuit capable of reducing a pulsating current of an output current even if the number of operating phases is changed. <P>SOLUTION: A DC/DC converter circuit 100 comprises: a plurality of converters 110 through 140 which are connected in parallel with each other and driven; and a controller 170 that generates a plurality of drive signals controlling respective switching operation of the plurality of converters. The controller 170 determines the number of converters to be driven, and when the number of converters to be driven is more than one, switches respective phase differences of the driving signals corresponding to each one of the plurality of converters according to the number of converters. <P>COPYRIGHT: (C)2012,JPO&INPIT |
