Product Summary

The LX1990 is a dual output current sink optimized for driving light emitting diodes. The evaluation board demonstrates how LX1990 enables precise current regulation in LED display lighting applications, yet requires far fewer parts than discrete solutions.

Parametrics

LX1990 absolute maximum ratings: (1)VDD: 2.7 to 5.5V; (2)VLOAD: 2 to 10V; (3)ENABLE: 0 to VDD; (4)PWM: 0 to VDD; (5)GND: 0V.

Features

LX1990 features: (1)Easily configured with 1 to 3 LED’s on each output; (2)Included rheostat allows output current to be set from 5 to 30mA; (3)Jumpers allow external PWM signal to burst dim the LED’s and an external enable control.
