Abstract

A controller includes a difference detector that detects a difference between a switching timing of a first channel of a switching power supply including a plurality of channels, and a switching timing of a second channel of the switching power supply, the plurality of channels being coupled in common to an input power supply and performing switching operations in response to clock signals, and a timing adjuster that, based on a detection result of the difference detector, increases a difference between a timing of a clock signal supplied to the first channel and a timing of a clock signal supplied to the second channel when the difference between the switching timing of the first channel and the switching timing of the second channel is smaller than a first value.
