  • LED dimming control technique for increasing the maximum PWM dimming ratio and avoiding LED flicker
    Publication number: 20070210725
    Abstract: Circuitry and methodology for providing LED dimming control in a LED driving system having a switching regulator for providing power supply to drive the LED. The switching regulator includes a switching circuit to which an oscillation signal is applied to control switching of the switching circuit. A dimming control input is supplied with a pulse-width modulation (PWM) dimming control signal to provide PWM dimming control of the LED. The dimming control input applies the PWM dimming control signal to control switching of the switching circuit. A synchronizing circuit is provided for synchronizing the oscillation signal to the PWM dimming control signal.
