MAX1747EUP+T

Overview

The MAX1747EUP+T is a triple-output DC-DC converter designed for TFT LCD bias generation. It accepts an input voltage range of 2.7V to 4.5V and provides three regulated outputs. The device integrates charge pump circuitry to generate the necessary negative and positive voltages required for liquid crystal display operation. It is housed in a 20-pin TSSOP package, suitable for space-constrained portable electronic applications requiring efficient power management for display panels.

Feature Summary

• Integrates triple-output conversion capability for simultaneous generation of positive and negative bias rails
• Optimized for direct interface with TFT LCD panel requirements
• Operates from low single-supply voltage sources suitable for battery-powered devices

Applications

• TFT LCD bias voltage generation
• Portable display systems
• Battery-powered consumer electronics

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging configuration when sourcing. Confirm the '+T' designation aligns with lead-free RoHS compliance standards required by your manufacturing process. Ensure the supplier source matches the official Analog Devices or Maxim Integrated distribution channels to guarantee component authenticity and traceability.

Selection Notes

Select this component when designing circuits that require integrated generation of multiple LCD bias voltages from a single low-voltage input. It is appropriate for applications where board space is limited and external inductors are undesirable. Consider the input voltage range compatibility with the system's primary power source before integration.

Part Context

This part belongs to the MAX1747 family of TFT LCD bias generators. It serves as a specialized power management solution within the broader portfolio of display driver support components offered by Analog Devices/Maxim Integrated, focusing on simplifying power architecture for small form-factor displays.

Replacement Considerations

Public documentation lists the MAX1747EUP+ as a related variant. Verify pinout and electrical specifications against current design requirements before substitution.
