LM3414HVMR/NOPB

Overview

The LM3414HVMR/NOPB is a Texas Instruments LED lighting driver IC belonging to the LM3414HV series. It utilizes a buck topology to deliver a constant current of 1 A to a single output channel. The device operates within an input voltage range of 4.5 V to 65 V and supports adjustable output voltage. It features an integrated switch and supports both analog and PWM dimming methods. The switching frequency is adjustable from 250 kHz to 1 MHz. The component is housed in an SO-PowerPad-8 package with SMD/SMT mounting style, rated for operation between -40°C and +125°C.

Feature Summary

Supports common anode capacitor constant current buck regulation for LED applications
Integrates high-side switch with thermal shutdown protection
Enables flexible brightness control through combined analog and PWM dimming capabilities

Applications

General LED lighting systems requiring constant current drive
High-voltage LED string configurations
Industrial or commercial illumination fixtures

Procurement Notes

Verify the specific suffix against official Texas Instruments documentation to confirm package type and reel specifications. Ensure compatibility with required operating temperature ranges and input voltage constraints before integration. Confirm RoHS compliance status via the manufacturer's latest datasheet revision.

Selection Notes

Select this component when designing buck converter circuits for high-voltage LED strings up to 65 V input. Consider the adjustable switching frequency for EMI optimization and the integrated switch for simplified bill of materials. Verify that the SO-PowerPad-8 package meets thermal and spatial requirements for the target enclosure design.

Part Context

This part belongs to the LM3414HV family of LED drivers designed for high-voltage applications. It differs from lower voltage variants by supporting inputs up to 65 V. The device is distinct from the LM3404HV series, which offers different input voltage ranges and dimming characteristics. It serves as a dedicated solution for driving LEDs without external MOSFETs.
