UBA2070T/N1,518

Overview

The UBA2070T/N1,518 is a CCFL controller manufactured by NXP USA Inc., designed for lighting and ballast applications. It operates within a frequency range of 40.5kHz to 100kHz and supports a supply voltage of 9V to 30V with a typical supply current of 5mA. The device is housed in a 16-SOIC package (0.154" width) and functions across an operating temperature range of -25°C to 100°C. This component serves as a dedicated driver for cold cathode fluorescent lamps.

Feature Summary

• Integrated control logic for efficient operation of cold cathode fluorescent lamps
• Fixed frequency oscillator design for stable lamp ignition and operation
• Compact surface-mount packaging suitable for space-constrained lighting modules

Applications

• Cold Cathode Fluorescent Lamp (CCFL) backlights
• LCD monitor and display backlighting systems
• Industrial and commercial lighting ballasts

Procurement Notes

Verify the specific suffix 'N1,518' against official NXP documentation to confirm pinout and electrical characteristics match your design requirements. Confirm RoHS compliance status and check for any tariff implications if shipping to restricted regions. Ensure the obsolete status does not impact long-term production viability.

Selection Notes

Select this component when a fixed-frequency CCFL driver is required for standard LCD backlighting. Compare against the UBA2014 for similar functionality or the UBA2074 for full-bridge configurations. Ensure the 16-SOIC footprint aligns with existing PCB layouts and that the 9V-30V input range matches the system power supply.

Part Context

This part belongs to the NXP UBA series of lighting controllers, specifically targeting CCFL applications. It complements other variants like the UBA2014 and UBA2074, offering a specialized solution for single-lamp or simple multi-lamp setups where fixed-frequency operation is sufficient for cost-effective display illumination.
