MAX1748EUE+T

Overview

The MAX1748EUE+T is a triple-output TFT-LCD DC-DC converter manufactured by Analog Devices Inc./Maxim Integrated. It integrates three switching regulators designed to generate the specific voltage rails required for Thin Film Transistor Liquid Crystal Display (TFT-LCD) panels. The device is housed in a 16-pin TSSOP package, suitable for surface-mount assembly. This integrated solution simplifies power supply design by combining multiple converters into a single component, reducing board space and component count for display applications.

Feature Summary

• Integrates three independent switching regulators within a single package
• Optimized for generating multiple voltage rails required by TFT-LCD panels
• Designed to reduce system component count and printed circuit board area

Applications

• Powering TFT-LCD displays
• Portable electronic devices requiring LCD backlight and panel power
• Embedded systems with display interfaces

Procurement Notes

Verify the exact suffix and tape-and-reel quantity against the manufacturer's current datasheet before ordering. Confirm that the 16-TSSOP package dimensions match your PCB footprint. Ensure compatibility with your target TFT-LCD voltage requirements, as this part provides fixed or regulated outputs specific to display drivers.

Selection Notes

Select this component when a compact, multi-rail power solution is needed specifically for TFT-LCD applications. It eliminates the need for discrete inductors and controllers for three separate rails. Verify that the output currents and voltages meet the specific demands of the target display panel before finalizing the design.

Part Context

This part belongs to the Maxim Integrated portfolio of power management ICs, now under Analog Devices. It is part of a family of solutions targeting portable electronics and display technologies. The MAX1748 series is distinct from general-purpose buck converters due to its specialized integration for LCD bias generation.

Replacement Considerations

Check for direct pin-compatible replacements within the MAX1748 family or newer generations from Analog Devices. Verify if alternative triple-output converters offer improved efficiency or different output configurations if the original part is obsolete.
