UCC2973PWTR

Overview

The UCC2973PWTR is a cold cathode fluorescent lamp (CCFL) driver controller manufactured by Texas Instruments. It operates in a TSSOP-8 package and is designed for LED and lighting applications. The device functions as a BICMOS controller, providing the necessary drive signals for CCFL backlights. It integrates essential control logic to manage the ignition and steady-state operation of the lamp.

Feature Summary

• Integrated BICMOS technology for robust CCFL driving
• Designed specifically for cold cathode fluorescent lamp applications
• Provides complete control logic for backlight systems

Applications

• CCFL backlight drivers
• LED lighting controllers
• Display illumination systems

Procurement Notes

Verify the specific suffix 'PWTR' corresponds to the TSSOP-8 package and tape-and-reel quantity when sourcing. Confirm RoHS compliance status through official datasheets or manufacturer notifications. Ensure the component matches the exact part number to avoid pinout mismatches in existing designs.

Selection Notes

Select this component for designs requiring dedicated CCFL control rather than general-purpose LED drivers. Evaluate the TSSOP-8 footprint constraints against available board space. Consider thermal performance requirements associated with the BICMOS process and package type during layout.

Part Context

This controller belongs to Texas Instruments' portfolio of display driver ICs. It serves as a specialized solution for managing high-voltage AC loads typical in CCFL technologies. The device supports integration into portable and industrial display modules requiring reliable backlight regulation.

Replacement Considerations

Consult official substitution guides for compatible CCFL controllers from the same family. Verify functional equivalence regarding drive capability and control interface before replacing.
