LM2751SD-B/NOPB TI LED Driver | 10-WSON (3x3) | 2.7-5.5V Input, 800mA Output

Product Overview

The LM2751SD-B/NOPB is a high-efficiency, low-noise, constant-current LED driver from Texas Instruments. It is designed to drive up to 10 LEDs in series or parallel configurations, providing a regulated output current up to 800 mA. The device operates from an input voltage range of 2.7V to 5.5V, making it suitable for battery-powered applications. The LM2751SD-B/NOPB features a 1.5 MHz fixed-frequency PWM boost converter, which allows for small external components and low output ripple. The device is available in a compact 10-pin WSON package (3x3 mm) for space-constrained designs.
