The LP5569 device is a programmable, easy-to-use 9-channel I2C LED driver designed to produce lighting effects for various applications. The LED driver is equipped with an internal SRAM memory for user-programmed sequences and three programmable LED engines, which allow operation without processor control. Autonomous operation reduces system power consumption when the processor is put in sleep mode.

A high-efficiency charge pump enables the driving of LEDs with high VF, even with 2.5-V input voltage. The LP5569 LED driver maintains good efficiency over a wide operational voltage range by autonomously selecting the best charge-pump gain based on LED forward voltage requirements.

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