DS3992Z-09P+

Overview

The DS3992Z-09P+ is a two-channel push-pull Cold Cathode Fluorescent Lamp (CCFL) controller manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 4.5V to 5.5V and draws 8 mA of supply current. The device supports dimming functionality and generates drive frequencies between 40kHz and 80kHz. It is housed in a 16-SOIC package with a width of 3.90mm and functions reliably across an operating temperature range of -40°C to 85°C.

Feature Summary

• Dual-channel push-pull architecture for independent CCFL backlight control
• Integrated analog dimming capability for brightness adjustment
• Fixed frequency operation optimized for standard CCFL requirements

Applications

• LCD panel backlighting systems
• Portable display devices
• Industrial monitor illumination

Procurement Notes

Verify component authenticity through authorized channels as the part is marked obsolete. Confirm RoHS compliance status and check for specific manufacturer lot codes. Ensure the 16-SOIC footprint matches design constraints. Review official product change notices for any historical manufacturing updates or material declarations prior to final integration.

Selection Notes

Select this component for designs requiring dual-channel CCFL driving with integrated dimming. Verify that the 40kHz to 80kHz frequency range aligns with the selected lamp specifications. Ensure the 16-SOIC package fits the PCB layout. Consider end-of-life status when planning long-term production cycles.
