LED Driver Six Output Programmable LED Current Sink

LED Driver LX1991ILQ LED Display Driver: This six channel current sink driver is ideal for controlling brightness and hue of high quality dimmable LED Displays High accuracy, dual mode dimming, and controlled current switching time provides consistent color hue, at brightness ratios of up to 1000:1, and keeps electro magnetic emissions in check. Its wide compliance voltage range combined with 43 volt breakdown cap- ability make the LX1991 ideal for automotive in-dash Displays Precision current control: Precision current mirror circuitry sets all channels to the same current with a single programming input. Sinking current value CAN be pro- grammed up to 30 mA per channel with a single resistor or potentiometer from ISET+ to ISET-. Channel to channel matching is ty- pically within 1 percent of channel mea at the rated output current. Dual Mode Dimming: Display dimming CAN be achieved by controlling either current amplitude or duty cycle, and both methods CAN be employed at the same time. By Microsemi Corporation
