LM3405AXMK/NOPB TI LED Driver | TSOT-23-6 | 1A Output, 2.7-5.5V Input

Product Overview

The LM3405AXMK/NOPB from Texas Instruments is a high-efficiency, constant-current LED driver designed for driving up to 1A of LED current. It operates from an input voltage range of 2.7V to 5.5V, making it suitable for low-voltage power sources. The device features a 1.6MHz fixed switching frequency, allowing for small external components and minimal output ripple. Housed in a compact TSOT-23-6 package, it is ideal for space-constrained applications.
