UBA2211CP/N1,112

Overview

The UBA2211CP/N1,112 is a high-voltage monolithic integrated circuit designed for driving compact fluorescent lamps (CFL) in half-bridge configurations. It integrates half-bridge power transistors rated at 120 V with an on-resistance of 2 ohms and a maximum ignition current of 3.5 A. The device includes an integrated bootstrap diode and a high-voltage supply to simplify system integration. It supports RMS lamp current control and features adjustable operating frequency to accommodate various burner designs.

Feature Summary

• Integrated half-bridge power transistors with bootstrap diode and high-voltage supply
• RMS lamp current control for stable operation
• Fast and smooth light out with boost and temperature-controlled timing
• Burner lifetime support via fixed frequency preheat and glow time control

Applications

• Compact fluorescent lamps up to 23 W for 120 V AC indoor applications
• Compact fluorescent lamps up to 23 W for 120 V AC outdoor applications

Procurement Notes

Verify the specific ordering suffix N1,112 against official NXP documentation to confirm package type and environmental compliance. Confirm availability status as this component may be discontinued or subject to limited supply constraints. Ensure compatibility with existing 120 V AC CFL ballast designs requiring half-bridge topology.

Selection Notes

Select this IC for 120 V AC CFL applications requiring integrated power switching and driver functionality. The adjustable operating frequency allows adaptation to different burner inductances. Verify that the required ignition current does not exceed the 3.5 A limit and that the thermal design accommodates the integrated power dissipation.

Part Context

This part belongs to the UBA2212 family of half-bridge power ICs for CFL lamps. It shares functional similarities with other members like the UBA2211BP but differs in package configuration. The CP variant specifically denotes the DIP14 plastic dual inline package suitable through-hole mounting.
