LM3410YQMFX/NOPB

Overview

The LM3410YQMFX/NOPB is a single-channel LED lighting driver IC from Texas Instruments, designed for automotive applications. It operates as a constant current boost controller with an integrated power switch. The device supports switching frequencies of 525 kHz and 1.6 MHz. It functions within an input voltage range up to 5.5 V and delivers a maximum output current of 5 A. The component is housed in a SOT-23-5 package and meets AEC-Q100 qualification standards. It operates reliably across a temperature range of -40°C to +125°C.

Feature Summary

• Integrates a high-side PFET power switch to minimize external component count.
• Provides precision constant current regulation for stable LED brightness.
• Includes thermal shutdown protection to safeguard against overheating conditions.

Applications

• Automotive exterior lighting systems
• LED headlamp modules
• Fog lamp drivers

Procurement Notes

Verify the specific suffix 'YQMF' corresponds to the required reel quantity and tape-and-reel packaging configuration before ordering. Confirm that the AEC-Q100 qualified version aligns with your automotive reliability requirements. Ensure the SOT-23-5 footprint matches your PCB design constraints. Cross-reference the datasheet for any recent process change notifications or lifecycle status updates to ensure long-term availability.

Selection Notes

Select this component when designing automotive LED circuits requiring a compact solution with an integrated switch. It is suitable for boost topologies where input voltages are below 5.5 V. Consider the available switching frequencies to optimize inductor size and efficiency. Verify that the thermal performance in the SOT-23-5 package meets the system's heat dissipation needs under maximum load conditions.

Part Context

This part belongs to the LM3410 family of LED drivers from Texas Instruments. It is specifically engineered for automotive environments, distinguishing it from general-purpose industrial variants. The 'NOPB' suffix indicates a lead-free and RoHS-compliant manufacturing process. It serves as a specialized solution for high-reliability lighting applications where space and component count are critical design factors.
