UBA2211AT/N1,518

Overview

The UBA2211AT/N1,518 is a half-bridge power integrated circuit designed for compact fluorescent lamp (CFL) applications. Manufactured by NXP Semiconductors, this component operates at a fixed frequency of 42.68 kHz and is housed in a 14-SOIC package with a width of 3.90 mm. It functions as a non-dimmable driver specifically engineered for CFL lamps, providing the necessary control and power management capabilities within a surface-mount configuration suitable for space-constrained lighting designs.

Feature Summary

• Integrated half-bridge power IC architecture optimized for CFL lamp drivers
• Fixed operating frequency of 42.68 kHz for stable lamp performance
• Non-dimmable design tailored for standard compact fluorescent lighting
• Surface-mount 14-SOIC package for compact board integration

Applications

• Compact fluorescent lamp (CFL) ballast controllers
• Non-dimmable CFL lighting fixtures
• Halogen-free electronic ballast circuits

Procurement Notes

Verify the specific suffix N1,518 to confirm RoHS compliance and packaging details. Confirm lead times and availability as distribution status may vary. Ensure compatibility with existing CFL driver designs requiring a 42.68 kHz fixed frequency operation. Check for end-of-life or last-time-buy notifications from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component for applications requiring a dedicated, non-dimmable CFL driver solution. The fixed 42.68 kHz frequency simplifies design compared to variable frequency alternatives. Ensure the system requires a 14-SOIC footprint. This part is suitable for general illumination where dimming functionality is not required.

Part Context

The UBA2211AT belongs to NXP's half-bridge power IC family specifically developed for CFL lamps. It integrates essential control and power stages into a single chip, reducing component count and board space. The device supports halogen-free manufacturing processes, aligning with environmental regulations for electronic components used in lighting systems.

Replacement Considerations

The UBA2211CT/N1,518 is a confirmed substitute within the same family, sharing identical electrical characteristics and pinout. Verify that any alternative replacement maintains the 42.68 kHz fixed frequency requirement and 14-SOIC package dimensions to ensure mechanical and functional compatibility.
