UC2872Q

Overview

The UC2872Q is a resonant lamp ballast controller manufactured by Texas Instruments, designed for display driver and CCFL backlight applications. It operates within an input voltage range of 4.5V to 24V and supports switching frequencies from 57kHz to 240kHz. The device is housed in a 20-pin LCC-20 package and functions across a temperature range of -40°C to 85°C.

Feature Summary

• Integrated resonant lamp ballast control for CCFL backlighting
• Supports variable frequency operation for display drivers

Applications

• CCFL backlight systems
• Resonant lamp ballasts
• Display driver circuits

Procurement Notes

Verify component status as the UC2872Q is listed as obsolete and no longer manufactured by Texas Instruments. Confirm availability of substitute parts such as the UC2872DW if sourcing new production units is required. Ensure compatibility with existing design constraints before procurement.

Selection Notes

Select this component for legacy designs requiring specific resonant ballast characteristics. Evaluate alternative controllers if current manufacturing support is necessary. Consider pinout and thermal requirements associated with the LCC-20 package during integration.

Part Context

This part belongs to the Texas Instruments family of lighting and ballast controllers. It is specifically categorized under display drivers and resonant lamp ballast solutions, distinct from general-purpose power management ICs or DC-DC converters.

Replacement Considerations

The UC2872DW is identified as a similar available substitute. Verify functional equivalence and pin compatibility before replacement.
