UBA2071AT/N1,118

Overview

The UBA2071AT/N1,118 is a half-bridge CCFL/EFL controller manufactured by NXP Semiconductors. It operates within a frequency range of 38 kHz to 42 kHz and requires a 14 V power supply with a current consumption of 1.5 mA. The device supports dimming functionality and is designed for surface mount installation in a 24-SOIC package (0.295 inch width). It functions reliably across an operating temperature range of -25°C to 100°C.

Feature Summary

• Integrated half-bridge driver architecture optimized for cold cathode fluorescent lamp applications
• Built-in dimming control capability for adjustable backlight intensity
• Designed for stable operation within specified industrial temperature ranges

Applications

• CCFL backlight drivers for LCD panels
• EFL lighting systems
• Industrial display backlights

Procurement Notes

Verify the obsolete status and availability through authorized distributors or secondary market suppliers like Rochester Electronics. Confirm that the 24-SOIC package dimensions match your PCB footprint requirements. Ensure the supplier provides valid traceability documentation for this discontinued component.

Selection Notes

Select this component when designing legacy CCFL or EFL backlight circuits requiring a dedicated half-bridge controller. Consider the specific 38-42 kHz operating frequency and 14 V supply constraints during schematic design. Evaluate the 24-SOIC package size against available board space.
