UCC3972PWTR

Overview

The UCC3972PWTR is a BiCMOS Cold Cathode Fluorescent Lamp (CCFL) controller designed for portable applications. It operates on a supply voltage range of 4.5V to 20V with a typical supply current of 7 mA. The device functions within a frequency range of 80kHz to 160kHz and utilizes a current-fed push-pull switcher configuration. It is housed in an 8-pin TSSOP package.

Feature Summary

• BiCMOS technology integration for efficient CCFL control
• Current-fed push-pull switching architecture
• Designed specifically for notebook and portable computing environments

Applications

• Notebook computer display backlighting
• Portable electronic device lighting systems
• CCFL ballast controller circuits

Procurement Notes

Verify the specific suffix 'TR' indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets prior to procurement. Ensure the component matches the required operating temperature range for the target application environment.

Selection Notes

Select this component for designs requiring integrated CCFL drive functionality in space-constrained portable devices. Evaluate the 80kHz to 160kHz operating frequency against transformer requirements. Consider the 4.5V to 20V input range compatibility with existing system power rails before finalizing the design.

Part Context

This part belongs to the UCC3972 family of BiCMOS controllers. It serves as a specialized driver for cold cathode fluorescent lamps, distinct from general-purpose LED drivers. The device integrates necessary control logic for portable electronics, differentiating it from discrete solution implementations.
