LM3414HVMRX/NOPB

Overview

The LM3414HVMRX/NOPB is a single-channel constant current buck LED driver from the LM3414HV series, manufactured by Texas Instruments. It operates with an input voltage range of 4.5 V to 65 V and delivers up to 1 A output current. The device features an adjustable switching frequency between 250 kHz and 1 MHz and supports both analog and PWM dimming. Packaged in an SO-PowerPad-8 (VQFN) format, it functions within a temperature range of -40°C to +125°C.

Feature Summary

• Integrates a high-side power switch for simplified circuit design
• Supports analog and pulse-width modulation dimming methods
• Includes thermal shutdown protection for enhanced reliability

Applications

• LED lighting drivers requiring common anode configuration
• High-voltage LED string illumination systems
• Industrial and commercial LED backlighting applications

Procurement Notes

Verify the specific suffix 'R' indicates reel packaging when ordering. Confirm RoHS compliance status through official datasheets. 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 for designs needing wide input voltage tolerance up to 65 V. The integrated switch reduces external component count compared to discrete solutions. Consider the SO-PowerPad-8 package for thermal performance in compact spaces. Validate that the required dimming method aligns with the supported analog or PWM inputs.

Part Context

This part belongs to the LM3414HV family of LED drivers designed for high-voltage applications. It serves as a direct replacement for the non-reel variant LM3414HVMR/NOPB, differing primarily in shipping packaging. The series is engineered for robust performance in demanding LED lighting environments.

Replacement Considerations

LM3414HVMR/NOPB is the tube-packaged equivalent of this reel-based component.
