Abstract:
Disclosed herein are a start-up circuit capable of reducing a leakage current to reduce power consumption, and a power device using the same. The start-up circuit includes: a bias unit connected between a first power source and a second power source and allowing a first current to flow from the first power source to the second power source according to a predetermined voltage; a first start unit connected to the bias unit and driving a second current to apply the predetermined voltage to the bias unit, and stopping driving the second current when a voltage received from the second power source reaches a first voltage; and a second start unit connected to the bias unit and driving a third current, the predetermined voltage being applied to the bias unit by the third current, and stopping driving the third current upon receiving a stop signal.
