The AL9910/A high voltage PWM LED driver-controller provides an efficient solution for offline high brightness LED lamps from rectified line voltages ranging from 85VAC up to 277VAC. The AL9910 drives external OSFETs at switching frequencies up to 300kHz, with the switching frequency determined by a single resistor.

The AL9910 topology creates a constant current through the LEDs providing constant light output. The output current is programmed by one external resistor and is ultimately determined by the external MOSFET chosen and therefore allows many low current LEDs to be driven as well as a few high current LEDs The LED brightness can be varied by both Linear and PWM dimming using the AL9910’s LD and PWM_D pins respectively.
