LM2757TMX/NOPB TI LED Driver | 12-DSBGA (1.64X1.24) | 5.5V Input, 800mA

Product Overview

The LM2757TMX/NOPB is a high-efficiency, low-noise, regulated charge pump LED driver from Texas Instruments. It is designed to drive up to 8 LEDs with a total output current of 800 mA. The device operates from an input voltage range of 2.7V to 5.5V, making it suitable for battery-powered applications. The LM2757 uses a fractional charge pump (1x/1.5x/2x) to maintain high efficiency across a wide range of input voltages. It features a 32-step exponential brightness control, soft-start, and overvoltage protection. The compact 12-DSBGA package (1.64mm x 1.24mm) is ideal for space-constrained designs.
