LM3410YSD/NOPB

Overview

The LM3410YSD/NOPB is a constant current LED driver IC from Texas Instruments, designed for boost and SEPIC topologies. It operates within an input voltage range of 2.7 V to 5.5 V and supports output voltages from 3 V to 24 V. The device delivers up to 2.8 A of output current with a switching frequency adjustable between 1.2 MHz and 2 MHz. Packaged in a WSON-6 (WSON-6 Exposed Pad) format, it functions reliably across a temperature range of -40°C to +125°C TJ.

Feature Summary

• Supports PWM dimming control for precise brightness adjustment
• Integrates enable/shutdown, soft start, and thermal shutdown protection
• Optimized for high-efficiency boost and SEPIC converter applications

Applications

• LED backlighting systems
• Portable electronic device illumination
• General-purpose LED lighting drivers

Procurement Notes

Verify the specific suffix 'YSD' corresponds to the required tape-and-reel packaging configuration and temperature grade. Confirm that the WSON-6 package dimensions align with your PCB footprint requirements. Ensure compatibility with the intended switching frequency settings for your power stage design.

Selection Notes

Select this component when a compact solution is needed for driving LEDs from low-voltage sources using boost or SEPIC architectures. It is suitable for designs requiring integrated thermal protection and PWM dimming capabilities without external complex control circuitry.

Part Context

This part belongs to the LM3410 series of LED drivers. It shares functional similarities with variants like LM3410XMY/NOPB but differs in package type (WSON-6 vs MSOP-PowerPad-8) and specific ordering suffixes indicating packaging or temperature variations.

Replacement Considerations

Direct substitutes include other LM3410 variants such as LM3410XMY/NOPB or LM3410XSDE/NOPB, provided the package footprint and electrical specifications match the existing design constraints.
