AL9910/AL9910A  
UNIVERSAL HIGH VOLTAGE HIGH BRIGHTNESS LED  
DRIVER  
Description  
Pin Assignments  
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 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 very resilient to transients at standard mains  
voltages. As well as standard SO-8 package the AL9910 is  
available in the thermally enhanced SO-8EP package.
