MAX1884EUP

Overview

The MAX1884EUP is a quad-output TFT LCD DC-DC converter manufactured by Maxim Integrated, now part of Analog Devices Inc. Housed in a TSSOP-20 surface-mount package, this component integrates four switching regulators designed to generate the specific voltage rails required for Thin Film Transistor Liquid Crystal Display (TFT LCD) panels. It operates with an input voltage range starting at 2.7V and supports output configurations tailored for display biasing applications.

Feature Summary

• Integrates four independent DC-DC converters within a single compact package
• Optimized specifically for generating power rails for TFT LCD panels
• Supports low-voltage operation suitable for portable battery-powered devices

Applications

• Power supply design for mobile phone displays
• Battery-operated handheld device screen drivers
• Portable media player backlight and panel biasing circuits

Procurement Notes

Verify the manufacturer status as Maxim Integrated is now part of Analog Devices Inc. Confirm the exact datasheet revision matches your design requirements. Check for end-of-life or obsolescence notices from the distributor. Ensure the TSSOP-20 footprint aligns with your PCB layout constraints before finalizing procurement.

Selection Notes

Select this component when a compact solution for multiple display voltages is needed. It replaces discrete regulator designs, saving board space. Consider the thermal performance of the TSSOP-20 package under load. Verify that the integrated outputs meet the specific current and voltage requirements of the target LCD panel without external boosting.

Part Context

This part belongs to the Maxim Integrated family of power management ICs specialized for display applications. It addresses the need for efficient, multi-rail power generation in space-constrained portable electronics. The integration of four converters reduces component count compared to using separate linear regulators or individual switching chips for each display rail.
