Abstract
A switching power supply includes: a switching type power supply circuit that converts an input voltage to generate an output voltage; and a control IC that executes feedback control that, based on a differential voltage between a target voltage and the output voltage from the power supply circuit, controls a switching element of the power supply circuit and causes the output voltage from the power supply circuit to converge to the target voltage. The control IC sets the target voltage for each predetermined period based on a value obtained by adding a preset value to the output voltage at a time of startup of the power supply circuit. Provided with this operation is a switching power supply that can precisely reduce an overshoot of the output voltage at the time of startup.
