Abstract
Disclosed is a power supply apparatus including a DC-DC converter implemented as one integrated circuit. A duty of a switching pulse of a DC-DC conversion unit is controlled according to a phase difference between a feedback clock signal and a reference clock signal having a frequency proportional to an output voltage of the DC-DC conversion unit. The duty of the switching pulse may be controlled from an output of a charge pump to be charged and discharged according to the phase difference signal between the feedback clock signal and the reference clock signal.
