MAX8740ETB+T

Overview

The MAX8740ETB+T is a high-performance step-up DC-DC converter manufactured by Analog Devices Inc./Maxim Integrated. It provides a regulated supply voltage for active-matrix, thin-film transistor (TFT), liquid crystal displays (LCDs). The device operates with an input voltage range suitable for single-cell lithium-ion battery applications. It integrates a power switch and control circuitry to efficiently boost voltage levels. The component is designed for portable electronics requiring stable power delivery to display panels.

Feature Summary

• Integrates a high-efficiency step-up DC-DC converter topology
• Provides regulated output voltage for TFT-LCD panel bias supplies
• Designed for operation from single-cell lithium-ion battery sources
• Includes integrated power switch and control logic

Applications

• Active-matrix thin-film transistor (TFT) LCD bias supplies
• Liquid crystal display (LCD) panel power management
• Portable electronic devices requiring boosted voltage rails
• Single-cell lithium-ion battery powered systems

Procurement Notes

Verify the exact suffix 'ETB+T' against the manufacturer's current datasheet to confirm package type and tape-and-reel specifications. Confirm RoHS compliance status as indicated by the '+' suffix in official documentation. Check for any recent lifecycle notices or obsolescence alerts directly from Analog Devices or Maxim Integrated before procurement planning.

Selection Notes

Select this component when a compact, high-efficiency step-up converter is needed specifically for TFT-LCD gate driver voltages. Ensure the application requires regulation from a single-cell lithium-ion source. Verify that the required output voltage and current capabilities align with the specific LCD panel specifications. Consider thermal performance within the 10-WFDFN exposed pad package for the target enclosure.

Part Context

This part belongs to the MAX8740 family of power management ICs focused on display driver applications. It is distinct from general-purpose converters by its optimization for TFT-LCD bias generation. The ETB+T designation specifies the 10-WFDFN package with an exposed thermal pad and lead-free construction. It complements other Maxim Integrated display power solutions for complete system designs.

Replacement Considerations

Consult the official Analog Devices replacement guide for direct pin-compatible alternatives. Verify electrical compatibility including switching frequency and output voltage ranges.
