MAX8753ETI+

Overview

The MAX8753ETI+T is a specialized power management integrated circuit designed for TFT LCD applications. It functions as a four-output converter, integrating step-up and linear regulators to provide necessary voltage rails for display panels. The device operates within an input voltage range of 2.6V to 5.5V, delivering four distinct output voltages ranging from 2.6V to 13V. It is housed in a 28-WFQFN package with an exposed pad and supports surface-mount installation. The component is rated for operation between 0°C and 85°C.

Feature Summary

• Integrates multiple regulator topologies including boost and LDO stages for comprehensive display power delivery
• Provides four independent output channels tailored for TFT LCD panel requirements
• Supports wide input voltage ranges suitable for single-cell battery or low-voltage bus systems

Applications

• TFT LCD panel power supply systems
• Mobile device display driver circuits
• Portable electronics requiring compact multi-rail regulation

Procurement Notes

Verify the specific suffix 'T' for reel packaging when ordering, as the base part number may denote tube packaging. Confirm current availability status as this component is listed as discontinued by major distributors. Ensure compatibility with existing PCB footprints for the 28-WFQFN package during replacement planning.

Selection Notes

Select this component for designs requiring a consolidated solution for TFT LCD bias generation. It eliminates the need for discrete boost converters and separate linear regulators. Consider the thermal performance of the exposed pad design for heat dissipation in dense layouts. Verify that the required output voltage levels fall within the specified 2.6V to 13V range.
