Abstract
A plurality of power conversion units each include an inductor, a switching circuit, and a PWM control IC. An MPU outputs control signals to the plurality of power conversion units. Output parts of the plurality of power conversion units are connected to an output terminal in a parallel manner. Operating number signal generating circuits of feedback signal generating circuits generate an operating number signal Sop on the basis of individual current signals based on inductor currents in the plurality of power conversion units, and output the operating number signal to the MPU. The MPU sets operations of the plurality of power conversion units on the basis of the operating number signal, and outputs the control signals including the settings of the operations of the power conversion units.
