Abstract: A circuit for driving a light source includes a voltage converter, a switch and a controller. The voltage converter converts an AC input voltage signal to a first rectified AC voltage signal. The voltage converter further generates an average signal proportional to an average voltage level of the first rectified AC voltage signal. The switch is coupled to the light source in series. The controller coupled to the voltage converter and the switch compares the first rectified AC voltage signal with the average signal to generate a pulse signal. The controller further generates a dimming control signal based on the pulse signal to control the switch thereby controlling dimming of the light source.

Abstract: A driving circuit for powering a light-emitting diode (LED) light source includes a converter circuit, an energy storage element and a switch element. The converter circuit provides a first output voltage on a first power line to provide power to the LED light source and provides a second output voltage on a second power line that is less than the first output voltage. The energy storage element is charged and discharged to regulate a current through the LED light source. The switch element operates in a first state during which the energy storage element is charged and operates in a second state during which the energy storage element is discharged. The converter circuit provides the second output voltage to maintain an operating voltage across the switch element less than the first output voltage during both the first state and the second state.
