LP5569 I2C RGB LED Driver
Texas Instruments LP5569 I2C RGB LED Driver 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 in sleep mode. A high-efficiency charge pump enables the driving of LEDs with high VF, even with a 2.5V input voltage. The LP5569 LED driver maintains good efficiency over a wide operating voltage range by autonomously selecting the best charge-pump gain based on LED forward voltage requirements.
