The LP5867 device is a small, high-performance
design, integrating six constant current sinks with
seven switching MOSFETs, driving up to 42 LED dots
or 14 RGB LED pixels. Every LED dot is supported
by 8-bit analog and 8-bit, or 16-bit, configurable PWM
dimming methods, providing smooth audible-noisefree dimming control. The LP5867EVM helps users
evaluate the features of Texas Instruments' LP5867
LED matrix driver. The LP5867 functions, RGB LED
matrix performance, and simple animation effects are
easily verified with this kit.
