LM3404HVMA

Overview

The LM3404HVMA is a monolithic switching regulator designed to deliver constant currents to high power LEDs. It operates with an input voltage range of 6 V to 75 V DC and provides a maximum output voltage of 73 V. The device supports a continuous output current of 1 A, with a peak capability of 1.2 A. It features PWM dimming control and operates at frequencies between 10 kHz and 1 MHz. The component functions as a buck converter topology and is housed in an 8-SOIC package.

Feature Summary

Monolithic switching regulator architecture for driving high power LEDs
Supports wide input voltage range from 6 V to 75 V DC
Enables precise LED brightness control via PWM dimming interface
Integrates internal power switch for compact design

Applications

Automotive lighting systems
Industrial illumination applications
General LED lighting driver circuits

Procurement Notes

Verify the specific suffix (e.g., NOPB) against the datasheet to confirm lead-free compliance and RoHS status. Ensure the ordering part number matches the required tape and reel or tube packaging configuration. Confirm that the SOIC-8 package dimensions align with the target PCB footprint before finalizing procurement orders.

Selection Notes

Select this component when a wide input voltage range up to 75 V is required for high-power LED applications. It is suitable for designs needing constant current regulation with PWM dimming capabilities. Consider the thermal performance within the -40°C to 125°C operating temperature range during circuit layout.

Part Context

This device belongs to the LM3404HV series, which includes variants like the LM3404HVMR/NOPB and LM3404HVMAX/NOPB. These parts share similar electrical characteristics but may differ in packaging options such as HSOP or standard SOIC-8 configurations. The series is optimized for automotive and industrial environments requiring robust LED drive solutions.
