Overview
The LM3410XMF/NOPB is a Texas Instruments LED lighting driver IC featuring a boost and SEPIC topology. It supports a single output with a maximum current of 2.8 A. The device operates within an input voltage range of 2.7 V to 5.5 V and provides an output voltage between 3 V and 24 V. Switching frequencies are adjustable from 1.2 MHz to 2 MHz. Packaged in an SOT-23-5 format, it functions reliably across temperatures from -40°C to +125°C.
Feature Summary
- Supports both boost and SEPIC topologies for flexible LED drive configurations
- Integrates constant current control for precise LED regulation
- Operates at high switching frequencies up to 2 MHz for compact design
Applications
- LED lighting driver circuits
- Portable illumination devices
- Battery-powered LED systems
Procurement Notes
Verify the specific suffix 'XMF' corresponds to the SOT-23-5 package variant when ordering. Confirm that the NOPB designation indicates lead-free compliance and RoHS adherence. Ensure the supplier provides official datasheets matching the manufacturer's documentation for accurate electrical parameter validation before integration.
Selection Notes
Select this component for applications requiring high-frequency operation and small form factors due to the SOT-23-5 package. Consider the 2.8 A output capability and wide input voltage range suitable for battery sources. Evaluate thermal management requirements given the extended temperature range and power dissipation characteristics inherent to the chosen topology.
Part Context
This part belongs to the LM3410 series of LED drivers from Texas Instruments. It shares functional similarities with other members like the LM3410XMY, differing primarily in packaging. The series is designed for efficient LED driving using boost or SEPIC architectures, targeting portable and automotive lighting markets.
Replacement Considerations
The LM3410XMY/NOPB serves as a direct alternative, offering identical electrical specifications but housed in an MSOP-PowerPAD-8 package instead of the SOT-23-5 footprint. Designers must verify board space and pinout compatibility when substituting.
