An LED driving device is provided to reduce a manufacturing cost by using a voltage regulator module and a gate driver as on-chip. An LED driving device includes a microcontroller(300), a voltage regulator(100), and a gate driver(200). The microcontroller produces control signals for driving an LED. The voltage regulator receives a first control signal from the microcontroller and controls the DC power to the LED. The gate driver receives a second control signal from the microcontroller and controls the PWM of the LED. The voltage regulator and the gate driver are comprised as an on-chip type. |
