DS3881E+T&R

Overview

The DS3881E+T&R is a single-channel CCFL controller manufactured by Analog Devices Inc./Maxim Integrated. It operates within a frequency range of 40kHz to 100kHz and requires a supply voltage of 4.75V to 5.25V. The device draws 12mA of supply current and supports dimming functionality. It is designed for surface mount installation in a 24-TSSOP package with dimensions of 0.173 inches (4.40mm) width. The component functions reliably across an operating temperature range of -40°C to +105°C.

Feature Summary

• Single-channel cold cathode fluorescent lamp control
• Integrated dimming capability
• Wide operating temperature range

Applications

• Laptop display backlighting systems
• Flat panel monitor illumination
• Industrial LCD screen lighting

Procurement Notes

Verify the specific suffix and tape/reel configuration against official datasheets before ordering. Confirm availability status as this component may be discontinued or subject to long lead times. Ensure the supplier provides valid traceability documentation matching the manufacturer's specifications.

Selection Notes

Select this component for applications requiring precise single-channel CCFL regulation. Consider the 24-TSSOP footprint for PCB layout constraints. Evaluate thermal management requirements given the extended industrial temperature rating and power dissipation characteristics inherent to the controller design.

Part Context

This part belongs to the Maxim Integrated CCFL controller family, now under Analog Devices. It serves as a dedicated driver for managing backlight intensity and stability in portable and stationary electronic displays. The series is known for integrating control logic with power stage drivers.

Replacement Considerations

DS3882E+T&R is a documented substitute offering similar CCFL control features in a 28-TSSOP package.
