The Texas Instruments LP5569ARTWR is a nine-channel I2C RGB LED driver designed for various illumination applications. This device provides high-accuracy current sinks, delivering up to 25.5 mA per channel with 8-bit individual current control. It supports flexible dimming capabilities through I2C and direct PWM input, featuring a 12-bit, 20-kHz internal PWM control that avoids audio noise.
The LP5569ARTWR operates within a supply voltage range of 2.5V to 5.5V and features a charge pump topology. It includes programmable LED engines for independent illumination control without requiring an active microcontroller. The device is housed in a 24-WQFN (4x4 mm) package, suitable for surface mount applications. Its operating temperature range is -40°C to 85°C, making it robust for various environmental conditions.
Key features include constant current regulation, power-save mode, and the ability to synchronize multiple devices. The driver also offers up to 256 instructions in SRAM for storing lighting sequences, enhancing its programmability for complex lighting patterns. This makes the LP5569ARTWR a versatile solution for applications requiring precise LED control and dynamic lighting effects.
