Abstract
A power supply control circuit is provided for preventing sudden inrush current which is produced when a power switch of an electronic device is turned on. The power supply control circuit includes a main power supply which receives an alternating current (AC) voltage and supplies a first predetermined voltage to a system and outputs a second predetermined voltage independent of an amplitude of the AC voltage, a subsidiary power supply which receives the second predetermined voltage and outputs a power voltage; and a controller which is operated by the power voltage and outputs a switch control signal to control a flow of the first predetermined voltage of the main power supply.
