LM3410XMFE/NOPB

Overview

The LM3410XMFE/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 compact SOT-23-5 format, it functions reliably across a temperature range of -40°C to +125°C.

Feature Summary

• Supports both boost and SEPIC converter topologies for flexible LED string configurations.
• Provides precise constant current regulation for driving high-power LEDs.
• Features adjustable switching frequency to optimize external component size and efficiency.

Applications

• Portable LED lighting devices
• Automotive interior illumination systems
• General solid-state lighting modules

Procurement Notes

Verify the specific suffix 'N/PB' indicates lead-free and RoHS compliance as per manufacturer standards. Confirm the SOT-23-5 package variant matches the design footprint requirements. Ensure the operating environment stays within the specified -40°C to +125°C thermal limits for reliable performance.

Selection Notes

Choose this model when a small SOT-23-5 package is required for space-constrained designs. Select for applications needing a wide input voltage range up to 5.5 V. Consider the 2.8 A current capability and adjustable frequency for optimizing inductor selection and system efficiency.

Part Context

This component belongs to the LM3410 series of LED drivers. It shares functional similarities with other parts in the family but differs in packaging and specific pinout configurations. The XMFE designation specifically identifies the SOT-23-5 surface-mount variant.

Replacement Considerations

The LM3410XMY/NOPB serves as a direct alternative, offering identical electrical specifications but utilizing an MSOP-PowerPad-8 package instead of the SOT-23-5 form factor.
