Texas Instruments  LP5569RTWR

The LP5569 device is a programmable, easy-to-use 9-channel I2CLED driver designed to produce lighting effects for various applications. The LED driver isequipped with an internal SRAM memory for user-programmed sequences and three programmable LEDengines, which allow operation without processor control. Autonomous operation reduces system powerconsumption when the processor is put in sleep mode.

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

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.
