LM3414MR/NOPB

Overview

The LM3414MR/NOPB is a single-output buck LED lighting driver IC from Texas Instruments. It supports an input voltage range of 4.5 V to 42 V and delivers a constant output current of 1 A. The device operates with an adjustable switching frequency between 250 kHz and 1 MHz. It features an SO-PowerPad-8 package and functions within a temperature range of -40°C to +125°C.

Feature Summary

Integrated power switch for simplified circuit design
Supports analog and PWM dimming control methods
Includes thermal shutdown protection for reliability

Applications

General LED lighting applications
Constant current LED drivers
Low voltage LED systems

Procurement Notes

Verify the specific suffix against official documentation, as variations may exist. Confirm RoHS compliance status through the manufacturer's datasheet. Ensure the SO-PowerPad-8 footprint matches your PCB layout requirements. Check humidity sensitivity levels for proper storage and handling procedures during assembly.

Selection Notes

Select this component when operating voltages do not exceed 42 V. Use for designs requiring a single channel of constant current regulation. Consider the integrated switch feature to reduce external component count. Verify that the required switching frequency falls within the 250 kHz to 1 MHz adjustable range.

Part Context

This part belongs to the LM3414 series of LED drivers. It differs from the LM3414HV variant by its lower maximum input voltage rating of 42 V compared to 65 V. Both share similar topologies and functionalities but are distinguished by their voltage handling capabilities.

Replacement Considerations

The LM3414HVMR/NOPB serves as a high-voltage alternative with a 65 V input limit. Verify compatibility regarding input voltage ranges before substitution.
