Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a power-supply device that has a simplified configuration and operates in an operating mode with reduced loss (high efficiency) even if the power consumption of a load fluctuates.SOLUTION: A power-supply device A determines an operating period and ON time of a switching element 1 so that a supply current Iout smoothed by a capacitor 3 is to be a predetermined current value, on the basis of an output voltage Vout of a coil 2 from an output voltage detection section 5.
