LM3410XSDE/NOPB

Overview

The LM3410XSDE/NOPB is a single-channel LED lighting driver IC from Texas Instruments, housed in a WSON-6 package. It supports Boost and SEPIC topologies with an output current capability of 2.8 A. The device operates on a supply voltage range of 2.7 V to 5.5 V and delivers output voltages between 3 V and 24 V. Its switching frequency ranges from 1.2 MHz to 2 MHz. The component functions within a temperature range of -40°C to +125°C.

Feature Summary

• Supports Boost and SEPIC converter topologies for flexible LED string configurations
• Integrates internal power switch for simplified circuit design
• Provides PWM dimming control capability for brightness adjustment
• Includes thermal shutdown protection for enhanced system reliability

Applications

• General LED illumination systems
• Portable electronic device backlighting
• Automotive interior lighting applications

Procurement Notes

Verify the specific suffix 'XSDE' corresponds to the WSON-6 package variant when sourcing. Confirm RoHS compliance status via the manufacturer's official documentation. Ensure the ordering part number matches the required tape and reel specifications for automated assembly processes.

Selection Notes

Select this component for designs requiring high efficiency in small form factors due to the compact WSON-6 footprint. Consider the 2.8 A output current limit when sizing external inductors and LEDs. Evaluate the 1.2 MHz to 2 MHz switching frequency range against EMI constraints and passive component size requirements.

Part Context

This device belongs to the LM3410 series of constant current LED drivers. It is designed for low-voltage input applications, distinguishing it from higher voltage variants like the LM3414. The series focuses on integrating power switches to reduce external component count.

Replacement Considerations

LM3410XMF/NOPB offers similar functionality in a SOT-23-5 package. LM3410YQMF/NOPB provides automotive qualification (AEC-Q100) with a different switching frequency range.
