LM3405XMKX/NOPB

Overview

The LM3405XMKX/NOPB is a constant current buck LED driver IC from Texas Instruments, designed for high-brightness LED applications. It operates with an input voltage range of 3V to 22V and delivers a regulated output current of 1A. The device features an integrated power switch and supports PWM dimming for brightness control. Operating at a switching frequency between 1.2MHz and 1.9MHz, it utilizes a TSOT-23-6 package. The component functions within a temperature range of -40°C to +125°C and includes thermal shutdown protection.

Feature Summary

Integrates a high-side N-channel power switch for compact design
Supports precise PWM dimming for adjustable LED brightness
Includes thermal shutdown protection for enhanced reliability

Applications

High-brightness LED lighting systems
Automotive exterior lighting modules
Portable battery-powered illumination devices

Procurement Notes

Verify the specific suffix 'X' indicates tape and reel packaging configuration distinct from standard tube variants. Confirm RoHS compliance status as indicated by the NOPB designation. Ensure compatibility with existing PCB footprints for the TSOT-23-6 thin package before integration into production designs.

Selection Notes

Select this component when a single-channel constant current solution is required for buck topology LED drivers. Consider the 1A output capability and wide input voltage range suitable for various supply conditions. Evaluate the TSOT-23-6 package size against available board space constraints and thermal management requirements for the target application environment.

Part Context

This part belongs to the LM3405 family of LED drivers manufactured by Texas Instruments. It shares core functionality with other variants like the LM3405AXMK/NOPB but differs in packaging and specific ordering suffixes. The series is engineered for efficient, compact LED regulation using synchronous buck conversion techniques.
