The LX1990 is a dual output current sink optimized for driving light emitting diodes. This low cost bipolar IC enables precise current regulation in LED display lighting applications, yet requires far fewer parts than discrete solutions. The LX1990 is supplied in a micro-miniature 6 lead MLP package featuring a 3 x 3 mm footprint, a profile of less than 1mm, and much improved thermal performance. Its two output sink currents are accurately matched and require only one resistor to program. Program current is only 1% of the output currents, and quiescent current is low, providing a very high efficiency driver for battery-powered displays. The LX1990 is based on a currentmirror architecture that transfers a reference current produced at the ISET pin to each of two open-collector current sinking outputs. The output stages multiply this reference current by 100 to sink independently regulated currents up to 30 mA.
