摘要：
The power supply device includes a power switch, a rectification diode which rectifies a supplied current in accordance with a switching operation of the power switch to generate an output current, and a switch control circuit which averages a detected sensing voltage corresponding to a sensing voltage which follows a current which flows through the power switch to generate an output current estimating voltage corresponding to the output current.
