LP5520TL/NOPB TI LED Driver | 25-USMD | 1.5A Total, 5-Channel

Product Overview

The LP5520TL/NOPB from Texas Instruments is a high-performance, 5-channel LED driver designed for portable and backlight applications. Housed in a compact 25-pin USMD package, it integrates a boost converter and current sinks to drive up to 5 LEDs with a total output current of 1.5A. The device operates from a 2.7V to 5.5V input supply and features programmable brightness control via a PWM interface. Its high efficiency and small footprint make it ideal for space-constrained designs.
