LP5868 8x18 LED Matrix Driver Texas Instruments LP5868 8x18 LED Matrix Driver integrates 8 MOSFETs for up to 144 LED dots or 48 RGB LEDs. The LP5868 supports both analog dimming and PWM dimming methods. For analog dimming, each LED dot can be adjusted with 256 steps. For PWM dimming, the integrated 8-bit or 16-bit configurable PWM generators enable smooth and audible-noise-free dimming control. Each LED dot can also be arbitrarily mapped into 8-bit group PWM to achieve dimming control together.
