A method of controlling a power driver for LED illumination may include receiving, by a power correction unit, an AC voltage from the outside, rectifying the received AC voltage into a DC voltage, and correcting a power factor of the rectified DC voltage; and receiving, by a DC/DC converter unit, the DC voltage from the power factor correction unit and converting the received DC voltage into a DC voltage which has a magnitude different from the received DC voltage and is supplied to an LED module. A skip control unit, which is disposed in the DC/DC converter unit, may be fed back with a current flowing in the LED module driven by receiving the output from the DC/DC converter unit to detect a magnitude of the current and output a signal for a skip mode control depending on the detected magnitude of the current.
