摘要：A power supply device coupled to a load includes a first switch that switches acurrent 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 connectionbetween an output terminal and the output of the first switch, a current sensing circuitthat senses a peak current value serving as a peak value of a current flowing through theinductor, and a control circuit that controls a first control terminal of the first switch anda second control terminal of the second switch and that calculates a value of an outputcurrent flowing through the load, based on an output value of a temporal coefficientcircuit coupled to one of a first control signal.
