  • Method and system for improving LED lifetime and color quality in dimming apparatus
    Patent number: 9572211
    Abstract: In a pulse width modulation light emitting diode (LED) controller an error amplifier and output load switch are synchronously controlled to prevent service life shortening current overshoot through the LEDs and slowing discharging currents causing color temperature shifting in the light output from the LEDs. A plurality of switching arrangements for the error amplifier and the compensation network may be provided in a single integrated circuit LED dimming controller, and outputs for controlling a variety of differently configured output power switch combinations for disconnecting or shorting the LEDs, or disconnecting the output capacitor during off times of the modulated dimming control signal.
    Type: Grant
