UCC2972PWG4

Overview

The UCC2972PWG4 is a BiCMOS Cold Cathode Fluorescent Lamp (CCFL) driver controller manufactured by Texas Instruments. It operates within a supply voltage range of 4.5V to 20V and supports frequencies between 80kHz and 160kHz. The device utilizes a current-fed push-pull switcher configuration. It is housed in an 8-pin TSSOP package with surface mount installation. The component functions as a display driver and controller for CCFL applications, designed for reliable operation in electronic lighting systems.

Feature Summary

• Integrated BiCMOS technology for efficient cold cathode fluorescent lamp driving
• Supports current-fed push-pull switcher configuration for stable lamp operation
• Operates across a wide frequency range suitable for various backlighting requirements

Applications

• Cold Cathode Fluorescent Lamp (CCFL) backlighting for displays
