Overview
The LM3410XQMF/NOPB is a constant current boost and SEPIC LED driver IC from Texas Instruments. It operates with 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 and features adjustable switching frequencies between 1.2 MHz and 2 MHz. It includes PWM dimming, enable/shutdown control, soft start, and thermal shutdown protection. Packaged in SOT-23-5, it functions within a temperature range of -40°C to +125°C.
Feature Summary
- Supports Boost and SEPIC topologies for flexible LED string configurations
- Integrates internal compensation to simplify external component count
- Provides precise PWM dimming control for brightness adjustment
- Includes thermal shutdown and soft start for enhanced system reliability
Applications
- Portable LED lighting systems
- Battery-powered illumination devices
- Automotive interior lighting applications
Procurement Notes
Verify the 'Q' suffix indicates automotive qualification (AEC-Q100) against the official datasheet, as standard LM3410XMF variants may lack this certification. Confirm the SOT-23-5 package type matches your PCB footprint requirements. Ensure the operating temperature range meets your specific environmental constraints before finalizing procurement.
Selection Notes
Select this component when designing high-efficiency LED drivers requiring both boost and SEPIC capabilities in a compact form factor. It is suitable for applications needing wide input voltage ranges and precise current regulation. Consider the internal compensation feature if minimizing external passive components is a priority for space-constrained designs.
Part Context
This part belongs to the LM3410 series of LED drivers, which are designed for high-frequency operation to reduce passive component size. The series typically includes variants like LM3410XMF and LM3410XMY, differing primarily in package types such as SOT-23-5 or MSOP-PowerPad-8. The XQ variant specifically targets automotive-grade reliability standards.
Replacement Considerations
LM3410XMF/NOPB: Pin-compatible alternative without specified automotive qualification. LM3410XMY/NOPB: Alternative in MSOP-PowerPad-8 package. Verify electrical parameters and package dimensions match your design requirements.
