摘要：
A light-emitting diode (LED) lighting device has an LED and a power supply including an inductor coupled to the LED. A cathode of the LED is coupled to the inductor opposite an anode of the LED. The inductor is coupled for receiving a first power signal. A transistor includes a conduction terminal coupled to the inductor to enable current through the inductor. A current from the first power signal is switched to generate a second power signal. A first diode includes an anode coupled to the inductor opposite the cathode of the LED. A controller includes a first terminal coupled to a cathode of the first diode and a second terminal coupled to a control terminal of the transistor. A zener diode is coupled to the first terminal of the controller. A capacitor is coupled between the first diode and inductor. A second diode is coupled to the first diode.
