Abstract

A switching power control circuit includes an analog-to-digital converter (ADC) configured to convert an analog direct current (DC) voltage into a digital voltage; a digital compensator configured to set a gain and phase characteristics of the digital voltage output from the ADC and output a digital compensation value; and a pulse generating circuit configured to generate at least one driving signal based on the digital compensation value, wherein the pulse generating circuit is switched by an ON/OFF signal for turning on or off an output of the driving signal from the pulse generating circuit and a control scheme selection signal for selecting a predetermined driving signal from the driving signal.
