DS3984T+

Overview

The DS3984T+ is a CCFL controller IC from the DS3984Z series, manufactured by Analog Devices Inc./Maxim Integrated. It operates within a frequency range of 40kHz to 80kHz and is housed in a 32-TQFP (7x7) package. This component functions as a dedicated driver for cold cathode fluorescent lamps, providing necessary control signals for backlighting applications.

Feature Summary

• Integrated CCFL control functionality
• Variable frequency operation capability
• Compact surface-mount packaging

Applications

• LCD panel backlighting systems
• Portable electronic device displays
• Industrial monitor illumination

Procurement Notes

Verify the specific suffix 'T+' against official Analog Devices documentation to confirm tape-and-reel packaging and lead-free status. Confirm the 32-TQFP footprint dimensions match your PCB design requirements. Check current lifecycle status as distribution data indicates potential discontinuation or limited availability for this specific part number.

Selection Notes

Select this component when a dedicated single-channel or multi-channel CCFL driver is required with integrated frequency control. Ensure the operating temperature range supports the intended environment. Compare pinout compatibility if replacing legacy Maxim Integrated designs with current Analog Devices equivalents.

Part Context

This part belongs to the DS3984 family of display drivers and controllers. It is specifically designed for managing cold cathode fluorescent lamps in liquid crystal displays. The manufacturer transitioned from Maxim Integrated to Analog Devices, maintaining product continuity for existing designs.

Replacement Considerations
