Abstract

See full text

A power factor correction circuit includes an inductor configured to receive an input voltage and supply an output voltage; a power switch connected to the inductor and configured to control an input current flowing through the inductor; and a switch controller configured to receive a feedback voltage including information on the output voltage and an auxiliary voltage including information on a voltage of the inductor and control an on/off operation of the power switch. The switch controller is further configured to operate in a first mode when the feedback voltage is less than a reference voltage, and operate in a second mode when the feedback voltage is greater than the reference voltage.
