Abstract
A power supply device has an output portion that generates an output voltage from an input voltage and supplies the output voltage to a load, an output feedback controller that drives the output portion by performing output feedback control, and a first detector that detects, by means of an electromagnetic induction method, a change in a first monitoring target current due to a load change. The output feedback controller reflects a detection result from the first detector into the output feedback control.
