Overview
The UCC2973PW is a BiCMOS cold cathode fluorescent lamp (CCFL) driver controller manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 20 V and draws a supply current of 7 mA. The device supports an operating frequency range of 80 kHz to 160 kHz, with specific documentation noting an operating frequency of 220 kHz for certain configurations. It functions without external dimming capabilities and is rated for an operating temperature range from -40°C to +85°C. The component is housed in an 8-pin TSSOP package.
Feature Summary
- BiCMOS technology integration for CCFL driver control
- External synchronization capability for system timing alignment
- Wide supply voltage tolerance for flexible power design
Applications
- Cold cathode fluorescent lamp backlighting systems
- LCD display driver circuits
- Industrial lighting ballast controllers
Procurement Notes
Verify the specific suffix designation against the manufacturer's official datasheet to confirm pinout and functional variations. Ensure the procurement channel provides original packaging to maintain moisture sensitivity integrity. Cross-reference the part number with the latest Texas Instruments documentation to validate compatibility with current manufacturing standards and RoHS compliance requirements before finalizing orders.
Selection Notes
Select this component when designing CCFL backlight drivers requiring BiCMOS performance characteristics. Consider the 8-pin TSSOP package constraints for PCB layout. Evaluate the 4.5 V to 20 V input range against the system power supply. Confirm that the absence of integrated dimming features aligns with the application's control architecture requirements.
Part Context
This part belongs to the UCC2972/UCC2973 series of display drivers and controllers. It is specifically engineered for cold cathode fluorescent lamp applications. The PW suffix indicates an 8-pin Thin Shrink Small Outline Package (TSSOP). It serves as a dedicated controller for managing CCFL ignition and steady-state operation in display systems.
Replacement Considerations
The UCC2972PW is a related variant within the same family. Verify functional equivalence and pin compatibility through official substitution lists before replacing.
