UBA2024AP/N1,112

Lighting, Ballast Controllers Overview

The UBA2024AP/N1,112 is a high-voltage monolithic integrated circuit designed as a compact fluorescent lamp (CFL) driver. It integrates full CFL controller functionality with high-voltage half-bridge transistors and an internal drive function featuring a high-voltage level shifter up to 550 V. The device includes a soft start function, adjustable internal oscillator, and minimum glow time control. Optimized for 230 V mains supplies, it supports electronically self-ballasted lamps up to 23 W.

• Electronically self-ballasted compact fluorescent lamps (CFL)
• High integration electronic ballast designs

Lighting, Ballast Controllers Procurement Notes

Verify the specific suffix N1,112 against official documentation to confirm package type and tape/reel specifications. Confirm current availability status as product lifecycles may change. Ensure application requirements match the 230 V mains optimization of this variant rather than the 110 V optimized versions within the family.

Lighting, Ballast Controllers Selection Notes

Select this component when designing for 230 V mains applications requiring a single-chip solution for CFL drivers. The pin-to-pin compatibility within the UBA2024 family allows for flexible power rating adjustments across different lamp wattages using the same application design. Verify thermal management capabilities to ensure junction temperature limits are not exceeded during operation.

Lighting, Ballast Controllers Part Context

This part belongs to the UBA2024 family of high-voltage monolithic integrated circuits from NXP Semiconductors. The family offers pin-to-pin compatibility between variants optimized for different mains voltages, such as 230 V and 110 V. This integration reduces component count and enables small form factor electronic ballasts for lighting applications.

Lighting, Ballast Controllers Replacement Considerations

Other members of the UBA2024 family are pin-to-pin compatible. Variants like UBA2024P or UBA2024T may be considered if voltage optimization differs. Verify that any substitute maintains the required half-bridge configuration and thermal performance characteristics.
