摘要
Disclosed are a power supply apparatus for an LED lighting and an LED lighting apparatus using the power supply apparatus. The LED lighting apparatus includes a power source unit configured to supply a rectified voltage, a voltage converter configured to include at least one first inductor and to convert the rectified voltage, an auxiliary coil configured to include a second inductor and to supply a detection voltage corresponding to the current of the first inductor of the voltage converter, a controller configured to control the current of the voltage converter using a driving pulse generated in response to a control signal and a sensing voltage, and a voltage regulation circuit configured to regulate the detection voltage and to supply the regulated voltage as an operating voltage for the controller.
