Overview
The UCC3972PWG4 is a BiCMOS cold cathode fluorescent lamp (CCFL) driver controller manufactured by Texas Instruments. It operates within a supply voltage range of 5V to 18V and draws a typical supply current of 7mA. The device functions as a dedicated CCFL driver controller with an operating frequency range of 80kHz to 160kHz. It is housed in an 8-TSSOP package, specifically the TSSOP-8 variant, designed for display backlighting applications.
Feature Summary
- BiCMOS technology integration for efficient CCFL control
- Low supply current consumption optimizing power efficiency
- Dedicated controller functionality for cold cathode fluorescent lamps
Applications
- Cold cathode fluorescent lamp (CCFL) backlighting systems
- Display driver and controller circuits
- LCD monitor backlight power supplies
Procurement Notes
Verify the specific suffix 'G4' indicates RoHS compliance and green manufacturing status as per Texas Instruments documentation. Confirm the package type matches the required 8-TSSOP footprint for PCB layout compatibility. Ensure the supplier provides official datasheets to validate the 5V-18V input range and 7mA supply current specifications before procurement.
Selection Notes
Select this component when designing CCFL-based display backlights requiring low quiescent current. The 80kHz to 160kHz operating frequency range suits standard transformer designs. Consider the 8-TSSOP package constraints for space-limited applications. Verify that the 5V to 18V supply voltage aligns with the system's available power rails.
Part Context
The UCC3972 series belongs to Texas Instruments' portfolio of PMIC lighting and ballast controllers. The UCC3972PWG4 is a specific variant within this family, distinguished by its BiCMOS process and TSSOP-8 packaging. It serves as a specialized solution for driving CCFLs in portable and desktop display equipment.
Replacement Considerations
Check for direct pin-compatible substitutes within the UCC3972 family. Verify if alternative CCFL drivers from other manufacturers meet the 7mA supply current and 80kHz-160kHz frequency requirements. Ensure any replacement maintains the 8-TSSOP form factor.
