The Texas Instruments LP5009RUKR is a 9-channel I2C constant-current RGB LED driver designed for various lighting applications. This device provides precise current control for each of the nine outputs, with a maximum of 35mA per channel when the supply voltage is 3.3V or higher.
Operating within a voltage range of 2.7V to 5.5V, the LP5009RUKR integrates a 12-bit, 29kHz PWM generator for each channel, enabling independent color mixing and brightness control. It supports both logarithmic and linear scale brightness control. The device features ultra-low quiescent current, with a typical value of 0.01mA in normal operation and a shutdown current of only 1µA.
Designed for surface mounting, the LP5009RUKR comes in a compact 20-WQFN (3x3) package. Its I2C interface allows for easy control and configuration, with features like programmable banks for R, G, and B colors and external hardware address pins for connecting multiple devices. The operating temperature range is -40°C to 85°C.
Key specifications include a 35mA maximum output current per channel, ±5% device-to-device and channel-to-channel error, and a 2.7V to 5.5V input voltage range. The device is suitable for applications requiring precise LED current regulation and dimming capabilities.
