LM3410XMFX/NOPB

Overview

The LM3410XMFX/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 a maximum output current of 2.8 A with a switching frequency adjustable between 1.2 MHz and 2 MHz. Packaged in a SOT-23-5 format, it functions reliably across temperatures from -40°C to +125°C.

Feature Summary

• Supports both Boost and SEPIC converter topologies for flexible LED string configurations
• Integrates internal power switch for compact circuit design
• Features programmable switching frequency to optimize external component size

Applications

• LED lighting modules requiring high efficiency
• Portable electronic devices with limited space constraints
• Battery-powered illumination systems

Procurement Notes

Verify the specific suffix 'X' indicates tape-and-reel packaging configuration when sourcing. Confirm that the 'MFX' designation corresponds to the SOT-23-5 package variant. Ensure compatibility with the intended operating temperature range and input voltage specifications before finalizing procurement orders.

Selection Notes

Select this component when designing circuits requiring both boost and SEPIC capabilities within a small footprint. Consider the 2.8 A current limit and 2 MHz maximum frequency for high-density applications. Evaluate thermal performance requirements given the SOT-23-5 package size and extended temperature rating.
