LM2757TM/NOPB TI LED Driver | 12-DSBGA | 5.5V Input, 750mA Flash

Product Overview

The LM2757TM/NOPB is a high-power, constant-current LED driver from Texas Instruments, designed for portable applications requiring high-brightness flash illumination. It integrates a 1.2A boost converter and a 750mA flash LED driver in a compact 12-DSBGA package. The device operates from a single Li-Ion battery (2.7V to 5.5V) and provides up to 750mA flash current with programmable current levels. Its low quiescent current and high efficiency make it ideal for camera phones, tablets, and other handheld devices.
