LM3409MYX/NOPB

Overview

The LM3409MYX/NOPB is a P-FET buck controller designed for high-power LED drivers. It operates within an input voltage range up to 42V and supports adjustable switch frequencies. The device features precision dimming control via analog or PWM signals, along with enable/shutdown capabilities. It includes thermal shutdown protection and functions as a constant current regulator. The component is housed in a 10-MSOP-PowerPAD package and is qualified to AEC-Q100 standards for automotive applications.

Feature Summary

Supports analog and PWM dimming for precise light intensity control
Integrates thermal shutdown protection for enhanced reliability
Enables external frequency adjustment for flexible design options

Applications

Automotive exterior lighting systems
High-power LED illumination modules
General-purpose DC-DC buck converter circuits

Procurement Notes

Verify the specific suffix 'MYX' against the manufacturer's official datasheet to confirm package type and tape-and-reel specifications. Ensure the 'NOPB' designation aligns with lead-free requirements. Cross-reference the AEC-Q100 qualification status if the application mandates automotive-grade certification. Confirm that the 42V rating meets the system's maximum input voltage constraints without exceeding absolute maximum ratings.

Selection Notes

Select this component when a P-channel MOSFET solution is preferred for high-side switching in LED driver topologies. It is suitable for designs requiring wide input voltage ranges and precise current regulation. Consider the 10-MSOP-PowerPAD package for space-constrained PCB layouts. Evaluate the need for external frequency setting components based on EMI requirements and efficiency targets.

Part Context

This part belongs to the LM3409 family of P-FET buck controllers from Texas Instruments. It shares functional similarities with the standard LM3409 but is distinguished by its specific packaging and automotive qualification. The HV variant offers higher voltage tolerance, while this model is optimized for 42V systems. It serves as a core control element in efficient LED driving applications.
