UBA2071TS/N1,118

Overview

The UBA2071TS/N1,118 is a half-bridge CCFL/EEL controller manufactured by NXP Semiconductors. It operates within a frequency range of 38 kHz to 42 kHz and supports dimming functionality. The device is powered by a 14 V supply with a current consumption of 1.5 mA. Designed for surface mount installation, it utilizes a 24-SOIC package (0.295 inch width). The component functions within an operating temperature range of -25°C to 100°C.

Feature Summary

• Integrated half-bridge driver topology for cold cathode fluorescent lamp applications
• Supports analog or PWM dimming control capabilities
• Operates at a fixed resonant frequency band between 38 kHz and 42 kHz

Applications

• Cold Cathode Fluorescent Lamp (CCFL) backlight drivers
• External Electron Excited Fluorescent Lamp (EEL) controllers
• Display illumination systems requiring half-bridge inversion

Procurement Notes

Verify the specific suffix 'N1,118' against official documentation to confirm tape-and-reel packaging specifications. Confirm that the 'TS' designation aligns with the required SOIC package variant. Ensure compatibility with existing board layouts for the 24-pin configuration before procurement.

Selection Notes

Select this component when designing lighting circuits that require a dedicated half-bridge driver for CCFL or EEL sources. It is suitable for applications needing operation within the 38–42 kHz range. Consider the 24-SOIC package constraints and the specified operating temperature limits during thermal design.
