LM3444MA/NOPB

Overview

The LM3444MA/NOPB is a single-channel AC-DC offline LED driver IC from Texas Instruments, designed for non-isolated buck topologies. It delivers a constant output current of 1 A and operates within an input voltage range of 8 V to 13 V. The device supports an adjustable switching frequency between 30 kHz and 1 MHz and features analog dimming capabilities. Packaged in an SOIC-8 surface-mount format, it functions reliably across a temperature range of -40°C to +125°C with a maximum supply current of 2.25 mA.

Feature Summary

Integrates thermal shutdown protection for enhanced operational safety
Supports analog dimming control for precise light intensity adjustment
Features adjustable switch frequency to optimize external component selection

Applications

Non-isolated AC-DC LED lighting drivers
General-purpose LED illumination systems
Offline LED driver circuits requiring buck topology

Procurement Notes

Verify the specific suffix 'MA' against the manufacturer's official datasheet to confirm package type and tape/reel specifications. Ensure the 'NOPB' designation aligns with current RoHS compliance requirements. Cross-reference the ordering information with the latest TI documentation to avoid discrepancies in package variants or regional restrictions.

Selection Notes

Select this component for applications requiring a single-channel constant current source with integrated thermal protection. The adjustable frequency allows flexibility in filter design. Confirm that the required output current does not exceed 1 A and that the operating environment stays within the specified -40°C to +125°C range. Validate compatibility with the intended buck converter topology.

Part Context

This part belongs to the LM3444 series of LED lighting drivers. It is specifically engineered for non-isolated applications, distinguishing it from isolated counterparts. The MA suffix indicates a specific package configuration within the broader product family, tailored for surface-mount assembly processes common in modern electronics manufacturing.
