PROBLEM TO BE SOLVED: To provide a DC/DC converter that can flexibly cope with various design conditions.SOLUTION: A pulse modulator 104 generates a pulse signal Shaving a duty ratio adjusted to match an output voltage Vto a predetermined target voltage. A distribution circuit 106 distributes the pulse signal Sreceived to N paths 108_1-108_N corresponding to N switching circuits 102_1-102_N. N driver circuits 110_1-110_N drive the switching circuits 102_1-102_N according to pulse signals S-Sthus distributed. The distribution circuit 106 is configured to switch at least between (1) an inphase mode in which the N distributed pulse signals Sare in phase and (2) a polyphase mode in which the N distributed pulse signals have a phase difference of 360/N degrees. |
