LP5810DDSDR TI LED Driver | 8-WSON(3X3) | 4-Ch, 25mA/Ch, I2C

Product Overview

The LP5810DDSDR from Texas Instruments is a high-performance, 4-channel constant-current LED driver designed for precise brightness control in a compact 8-WSON (3x3 mm) package. It supports I2C interface for flexible dimming and features ultra-low quiescent current, making it ideal for battery-powered applications. Each channel can sink up to 25 mA with ±3% current accuracy, ensuring uniform LED illumination.
