Abstract
A power supply device coupled to a load includes a first switch that switches a current input from an input terminal, a second switch that switches between a ground potential and an output of the first switch, an inductor that establishes a connection between an output terminal and the output of the first switch, a current sensing circuit that senses a peak current value serving as a peak value of a current flowing through the inductor, and a control circuit that controls a first control terminal of the first switch and a second control terminal of the second switch and that calculates a value of an output current flowing through the load, based on an output value of a temporal coefficient circuit coupled to one of a first control signal.
