efficient solution for offline high brightness LED lamps from rectified
line voltages ranging from 85V AC up to 277V AC . The AL9910 drives

external MOSFETs 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. The PWM_D
input operates with duty ratio of 0-100% and frequency of up to
several kHz.
The AL9910 can withstand input voltages up to 500V which makes it
