Abstract
An integrated light-emitting diode (LED) driver circuit includes a bi-directional power line communication (PLC) unit, a power conversion module, and a constant current (CC)/constant voltage (CV) control unit. The bi-directional PLC unit receives an AC voltage, and converts a modulation signal on the AC voltage to generate a light-dimming control signal. The power conversion module receives the AC voltage and converts the AC voltage to generate an output voltage. The CC/CV control unit receives the light-dimming control signal to generate a dimming constant current or a dimming constant voltage. The integrated LED driver circuit outputs the dimming constant current or the dimming constant voltage and the output voltage to drive a LED string.
