LP5810DDSDR

LED Driver IC Overview

The LP5810DDSDR is a Texas Instruments LED lighting driver IC featuring four independent linear constant-current channels. It operates within a supply voltage range of 2.7 V to 5.5 V, supporting output voltages from 0 V to 5.5 V. Each channel provides an adjustable output current ranging from 100 µA to 25.5 mA, with specific documentation citing a maximum per-channel current of 51 mA. The device supports I2C and PWM dimming interfaces at frequencies up to 1 MHz. Designed for surface-mount assembly in an 8-WSON (3x3) package, it functions reliably across a temperature range of -40°C to +85°C.
