LP5867 evaluation module
LP5867WCSPEVM
概述
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.
