Abstract
Disclosed herein is a gate driver. The gate driver according to an exemplary embodiment of the present invention includes: a first power switch sourcing current according to voltage applied by a voltage source; a second power switch connected with the first power switch in series and sinking current according to the voltage applied by the voltage source; and a speed booster receiving a voltage pulse from the outside to output peak current so as to make a turn on/off operation of the first power switch fast. As set forth above, according to the exemplary embodiments of the present invention, it is possible to improve the driving speed of the gate driver without increasing the current of the current source by further including the speed booster configured of the plurality of MOSFETs and the capacitor.
