Abstract
Provided is a load driving device controlling a drive of a load including a driver for periodically turning on/off a current according to a switching clock signal and supplying a average driving current to the load. Further provided is a dimming controller for controlling the driver to turn on/off the drive of the load based on a dimming step. Also provided is a controller for controlling at least one of the driver and the dimming controller so as to make a step interval of the dimming step and a switching clock period of the switching clock signal the same. A load driving device is provided that is capable of stably controlling the dimming of a drive of a load, by improving a linear response characteristic of a driving current according to a dimming control.
