LP5018DGSR TI LED Driver | 28-VSSOP | 18-Channel, I2C, 5.5V

Product Overview

The LP5018DGSR from Texas Instruments is a high-performance, 18-channel constant-current LED driver designed for precise brightness control in a wide range of lighting applications. Housed in a compact 28-VSSOP package, this device integrates an I2C-compatible interface for easy digital control, enabling independent PWM dimming of each channel. With a wide input voltage range of 2.7V to 5.5V and a maximum output current of 35 mA per channel, the LP5018DGSR is ideal for powering RGB LEDs, indicator lights, and display backlighting in portable and industrial systems. Its low quiescent current and thermal shutdown protection ensure reliable operation in space-constrained designs.
