Abstract

A display apparatus includes a power supply for providing power, a circuit board including an integrated circuit (IC) with a central processing unit (CPU) that processes an image signal; and a display configured to display an image corresponding to the image signal; the IC includes a power controller configured to monitor a voltage level of a core voltage provided by the power supply to the IC and adjust a phase margin of a voltage corresponding to a voltage detected by the monitoring. Thus, a phase margin may be adjusted in accordance with a voltage of an IC, thereby compensating for voltage fluctuation due to instantaneously varying ripples and thus stably driving a system.
