CLOCK GENERATOR OF WIRELESS POWER RECEIVING DEVICE AND METHOD FOR GENERATING THE CLOCK

摘要

The present invention relates to an apparatus and a method for generating a clock to control a DC-DC converter of a wireless power receiving device in order to improve energy transmission efficiency of a wireless power transmission system. According to the present invention, the apparatus generates a clock to control the DC-DC converter by using a wireless power transmission signal received from an external wireless power transmission device and controls the DC-DC converter by using the generated clock, thereby reducing power consumption for the generation of an internal clock while receiving wireless power and increasing the transmission efficiency of the wireless power transmission system.
