Abstract
In accordance with an embodiment, a control circuit for controlling a light emitting diode includes a first switching circuit having first and second inputs and an output and a second switching circuit having at least first and second inputs and an output, the first input coupled to the second input of the first switching circuit. Another embodiment includes a method for reducing flicker by generating an adjusted rectified voltage in response to a TRIAC dimmer signal from a TRIAC dimmer and a switching current in response to the adjusted rectified voltage being greater than a first reference voltage. The switching current is decreased in response to the adjusted rectified voltage becoming less than the first reference voltage. The TRIAC dimmer is turned off in response to decreasing the switching current.
