LM3556TME/NOPB TI LED Driver | 16-DSBGA | 2.5V-5.5V, 1.5A Flash

Product Overview

The LM3556TME/NOPB is a high-power, synchronous boost LED driver from Texas Instruments, designed to drive up to 1.5A of LED current for camera flash and torch applications. It operates from a single Li-Ion cell with input voltage range of 2.5V to 5.5V. The device integrates a 1.5A, 2MHz boost converter with programmable current limit and flash duration, ensuring consistent light output. Housed in a compact 16-DSBGA package (2.0mm x 2.0mm), it is ideal for space-constrained portable electronics.
