Overview
The UCC2972PW is a BiCMOS push-pull cold cathode fluorescent lamp (CCFL) driver controller manufactured by Texas Instruments. Designed for display backlighting applications, it operates within a supply voltage range of 4.5V to 20V and supports switching frequencies between 80kHz and 160kHz. The device utilizes a current-fed push-pull switcher configuration to optimize CCFL performance and lifespan. It is housed in an 8-pin TSSOP package and functions reliably across an operating temperature range of -40°C to +85°C.
Feature Summary
- BiCMOS technology integration for efficient CCFL driving
- Push-pull current-fed switcher configuration
- Optimized for extended lamp lifespan and performance
Applications
- LCD panel backlighting systems
- Cold cathode fluorescent lamp drivers
- Display controller circuits
Procurement Notes
Verify the specific revision level (e.g., Rev. C) against the latest official datasheet to ensure compatibility with design requirements. Confirm that the TSSOP-8 package matches the PCB footprint. Ensure the supply voltage and frequency ranges align with the target CCFL specifications before procurement.
Selection Notes
Select this component when a dedicated BiCMOS controller for CCFL backlights is required. It is suitable for designs needing a push-pull topology with a wide input voltage range. Consider the thermal characteristics and operating temperature limits (-40°C to +85°C) relative to the final application environment.
Part Context
The UCC2972 belongs to the UCC2972 series of display drivers and controllers from Texas Instruments. It is specifically engineered for cold cathode fluorescent lamps, distinguishing itself from general-purpose LED drivers through its specialized push-pull architecture and frequency control capabilities tailored for CCFL operation.
Replacement Considerations
Consult official substitution guides or contact Texas Instruments directly for verified alternative part numbers. Do not assume cross-compatibility with other CCFL controllers without verifying pinout, electrical parameters, and functional equivalence.
