Abstract
Disclosed are a switch control circuit, a converter including the same, and a driving method thereof. The converter includes an inductor for storing energy of an input end and providing the same to an output end, a first switch coupled between the inductor and a ground, and a switch control circuit for controlling the first switch by comparing a ramp voltage that corresponds to a current that flows through the first switch and a first voltage that corresponds to an output voltage of the output end. The switch control circuit compares the ramp voltage and the first reference voltage to change the slope of the ramp voltage.
