  • LED driver circuits and methods
    Patent number: 7843147
    Abstract: An LED driver circuit may include dimming circuitry. In particular, the LED driver circuit may include a switching converter, an LED and a switch. The LED may be electrically connected to the switching converter and the switch may be connected in parallel with the LED. The switching converter and/or the switch may be configured to be controlled to achieve dimming of the LED. Current may be supplied to the LED and the switch may be turned on and off to dim the LED. The switching converter coupled to the LED may include a switching element in series with an inductor and the LED. In such case, the switching element may be turned on to supply current to the LED and the inductor, and the switch may be turned on and off to dim the LED.
