UBA2071T/N1,118

Overview

The UBA2071T/N1,118 is a half-bridge CCFL/EEL controller manufactured by NXP. 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

• Integrates half-bridge driver architecture for cold cathode fluorescent lamp applications
• Supports adjustable dimming control capabilities
• Operates at fixed frequencies between 38 kHz and 42 kHz

Applications

• CCFL backlight drivers
• EEL lighting systems

Procurement Notes

Verify the obsolete status of this component before procurement planning. Confirm availability through authorized distributors or secondary market suppliers like Rochester Electronics. Ensure compatibility with existing design specifications as no longer manufactured by NXP. Check lead times carefully due to potential supply chain constraints associated with end-of-life products.

Selection Notes

Select this component specifically for legacy CCFL or EEL designs requiring a 38–42 kHz half-bridge drive. Consider the 24-SOIC package constraints and -25°C to 100°C operating range. Evaluate alternative modern LED drivers if new designs are permitted, as this part is discontinued. Verify pinout compatibility if replacing older versions.

Part Context

This part belongs to NXP's lighting driver portfolio, specifically targeting cold cathode and external electrode fluorescent lamps. It represents a specialized analog solution for backlighting in displays and signage. The product line has been succeeded by newer technologies, leading to its discontinuation status while remaining available through surplus channels.

Replacement Considerations

No public confirmed substitute part numbers are available.
