LM3447MTX/NOPB

Overview

The LM3447MTX/NOPB is a primary-side power regulation controller designed for power factor correction (PFC) and flyback applications. It integrates PFC control with forward and reverse phase dimming capabilities. The device operates within an input voltage range of 8.5 V to 20 V, delivering up to 1.5 A output current. It supports Boost and Flyback topologies with a switching frequency between 180 Hz and 700 Hz. The component functions reliably across a temperature range of -40°C to +125°C TJ.

Feature Summary

Integrates primary-side power regulation with power factor correction
Supports both forward and reverse phase dimming methods
Enables compact designs by eliminating secondary side feedback components

Applications

LED lighting for industrial equipment
A-lamp fixtures
Refrigeration lighting systems
Stage and studio lighting

Procurement Notes

Verify the specific suffix 'X' indicates tape and reel packaging when sourcing. Confirm RoHS compliance status through official Texas Instruments documentation. Ensure the ordering part number matches the exact package type required for your assembly process. Cross-reference the datasheet revision date to confirm technical accuracy before finalizing procurement specifications.

Selection Notes

Select this controller for applications requiring integrated PFC and dimming in a single IC. It is suitable for designs needing operation within the 8.5 V to 20 V input range. Consider the TSSOP-14 package constraints for thermal management. Verify compatibility with the desired LED load current requirements of up to 1.5 A.

Part Context
