UBA2211CT/N1,518

Overview

The UBA2211CT/N1,518 is a high-voltage monolithic integrated circuit designed for driving Compact Fluorescent Lamps (CFL). It operates as a non-dimmable driver controller with a fixed switching frequency of 42.68 kHz. The component is housed in a 14-SO package and is classified under Lighting Ballast Controllers within the Power Management IC category.

Feature Summary

• High-voltage monolithic integration for CFL applications
• Non-dimmable driver controller functionality
• Fixed operating frequency design

Applications

• Compact Fluorescent Lamp (CFL) drivers
• Lighting ballast controllers

Procurement Notes

Verify part status carefully as this specific variant may be marked obsolete or subject to last-time buy restrictions. Confirm the exact suffix N1,518 matches your bill of materials, as minor variations can affect availability. Check moisture sensitivity level ratings if storage conditions are critical to your assembly process.

Selection Notes

Select this component specifically for non-dimmable CFL lamp designs requiring a fixed 42.68 kHz operation. Ensure the application does not require dimming capabilities, as this IC lacks that feature. Verify compatibility with the required high-voltage input specifications and SO package constraints for the target PCB layout.

Part Context

This IC belongs to the UBA2211 family of high-voltage monolithic circuits from NXP Semiconductors. These components are engineered specifically for compact fluorescent lighting systems. The family provides integrated solutions for lamp ignition and stabilization without external complex control logic.

Replacement Considerations

UBA2211AT/N1,518 is a documented substitute within the same family offering similar CFL/TL driver capabilities.
