The LP5810 is a 4-channel RGBW LED driver with autonomous animation engine control. The device has ultra-low normal operation current with 0.4-mA (typical) when illuminate LEDs.
Both analog dimming and PWM dimming methods are adopted to achieve powerful dimming performance. The output current of each LED can be adjusted with 256 steps from 0.1 mA to 25.5 mA or 0.2 mA to 51 mA. The 8-bit PWM generator enables smooth and audible-noise-free dimming control for LED brightness.
The autonomous animation engine can significantly reduce the real-time loading of controller. Each LED can be configured through the related registers to realize vivid and fancy lighting effects. The device can generate 6-MHz clock signal and use it for synchronizing the lighting effects among multiple devices.
