Overview
The UCC3972PW 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 switching frequencies between 80kHz and 160kHz. The device utilizes a current-fed push-pull switcher configuration to drive CCFL lamps. It is housed in an 8-pin TSSOP package with dimensions of 0.173 inches width (4.40mm). The component functions as a dedicated display driver and controller for backlight applications.
Feature Summary
- BiCMOS technology integration for efficient CCFL control
- Current-fed push-pull switcher architecture
- Integrated lamp intensity control capability
Applications
- Cold Cathode Fluorescent Lamp (CCFL) backlighting systems
- Display driver controllers for LCD panels
- Industrial and commercial lighting control circuits
Procurement Notes
Verify the specific suffix 'PW' confirms the TSSOP-8 package variant. Confirm RoHS compliance status through official datasheets. Ensure the operating temperature range meets system requirements, typically spanning -40°C to +85°C or 0°C to 70°C depending on the specific grade. Cross-reference manufacturer part numbers to avoid confusion with similar series components.
Selection Notes
Select this component when a dedicated CCFL driver with integrated intensity control is required. The BiCMOS process offers a balance of performance and power efficiency. Consider the 80kHz to 160kHz frequency range for transformer design compatibility. The TSSOP-8 package suits space-constrained surface-mount designs. Verify supply voltage limits against the target application's power rail.
Part Context
The UCC3972 belongs to Texas Instruments' family of display drivers and controllers. It is specifically designed for cold cathode fluorescent lamp applications. The PW suffix denotes the plastic small outline package variant. This component serves as a key interface between logic-level control signals and high-voltage lamp requirements.
Replacement Considerations
Check for direct pin-compatible substitutes within the same TI family. Verify electrical parameters such as supply voltage and frequency ranges match exactly. Ensure package dimensions are identical for mechanical fit. Consult official substitution guides for validated alternatives.
