Abstract:
The present disclosure discloses a light-emitting diode (LED) driver comprising a controller and a main circuit. The controller is configured to receive a dimming signal for dimming an LED load and use a current hysteresis control to generate a control signal, wherein a hysteresis width of the current hysteresis control varies with the dimming signal. The main circuit comprises a front-end stage configured to receive an AC input voltage and output a DC bus voltage, and a back-end stage configured to receive the bus voltage and responsive to the control signal, output a desired drive current through output terminals to the LED load so as to produce a target illumination intensity. The present disclosure widens the dimming depth of analog dimming in the LED dimming technology, achieves deep dimming and satisfies good dimming linearity in the entire dimming range.

Claim (Index 5):
The LED driver as claimed in  claim 4 , wherein the first module ( 21 ) is further configured to produce the threshold voltage (V th ) based on the dimming signal (DS) and provide the threshold voltage to the second module.
