MAX1765EUE+T

Overview

The MAX1765EUE+T is a dual-output power management integrated circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It combines a synchronous step-up (boost) DC-DC converter with a low-dropout (LDO) linear regulator in a single package. The boost converter provides an output current of up to 800mA and operates at a switching frequency of 1MHz. The device supports an input voltage range from 700mV to 5.5V, delivering regulated outputs between 2.5V and 5.5V. It is housed in a 16-pin TSSOP-EP package and is rated for operation within a temperature range of -40°C to +85°C.

Feature Summary

• Integrates a synchronous boost converter and an LDO linear regulator for combined power management
• Features low-noise architecture suitable for sensitive analog circuits
• Supports wide input voltage ranges starting from very low levels

Applications

• Portable battery-powered devices requiring efficient voltage boosting
• Systems needing simultaneous high-current boost and low-noise LDO regulation
• Industrial control modules operating in extended temperature environments

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor certificates. Ensure the supplier provides traceability data consistent with Analog Devices quality standards. Cross-reference the full part number against current product lifecycle notices to confirm active status.

Selection Notes

Select this component when space-constrained designs require both efficient step-up conversion and clean linear regulation. The 1MHz switching frequency allows for smaller external inductors and capacitors compared to lower-frequency alternatives. Consider the thermal performance of the exposed pad TSSOP-EP package for heat dissipation requirements in enclosed enclosures.

Part Context

This part belongs to the MAX1765 family of mixed-signal power management ICs. It is designed to replace discrete solutions combining separate boost converters and LDOs. The integration reduces board area and simplifies bill of materials for portable electronics and industrial instrumentation applications requiring reliable power delivery.

Replacement Considerations

Check for direct pin-compatible successors within the Maxim Integrated portfolio. Verify if newer generations offer improved efficiency or wider input voltage ranges while maintaining the same 16-pin TSSOP-EP footprint.
