MAX1997ETJ

Overview

The MAX1997ETJ+T is a specialized power management integrated circuit designed for TFT LCD applications. It functions as a quintuple-output DC-DC converter, providing five distinct regulated voltage rails required for display panel operation. The device integrates fault protection mechanisms and a dedicated VCOM buffer to ensure stable video signal integrity. Operating within an industrial temperature range of -40°C to +85°C, it utilizes a 32-pin TQFN package with an exposed pad for efficient thermal dissipation.

Feature Summary

• Integrates five independent output channels to supply multiple voltage rails for TFT LCD panels
• Includes a dedicated VCOM buffer to maintain precise common-mode voltage stability
• Features built-in fault protection circuits to safeguard the display system against abnormal conditions

Applications

• TFT LCD panel power supply systems
• Portable electronic displays requiring multi-rail regulation
• Industrial display modules with fault tolerance requirements

Procurement Notes

Verify the exact suffix (e.g., ETJ+) against the manufacturer's current datasheet to confirm pinout and electrical specifications. Confirm availability status as distribution channels may list limited stock or end-of-life statuses. Ensure the ordering part number matches the specific package variant required for your PCB layout.

Selection Notes

Select this component when a single IC solution is needed to drive multiple voltages for a TFT LCD interface. It is suitable for designs prioritizing board space reduction by consolidating five regulators into one package. Consider the thermal performance of the TQFN-EP-32 package relative to the total power dissipation of all five outputs in the final application.

Part Context

This part belongs to the Maxim Integrated portfolio of power management solutions, specifically targeting display driver applications. It replaces discrete regulator arrangements, simplifying the bill of materials. The device is categorized under PMICs for portable electronics and display systems.

Replacement Considerations

Check for direct cross-references in Analog Devices' replacement guides. Verify if newer revisions of the MAX1997 series offer improved efficiency or updated packaging options.
