Overview

All trademarks are the property of their respective owners.

The LP5569 device enters power-save mode when LEDs are not active, lowering idle-currentconsumption considerably. A flexible digital interface allows the connection of up to eight LP5569devices with a unique I2C slave address for each device in the samesystem, which supports synchronization of the lighting effects among all devices.
