MAX1765EUE+

Overview

The MAX1765EUE+ is a dual-output power management integrated circuit manufactured by Analog Devices Inc./Maxim Integrated. It combines a synchronous boost converter and a low-dropout linear regulator within a single package. The device operates from an input voltage range of 0.7V to 5.5V. The boost output provides up to 800mA, while the LDO output delivers up to 500mA. It features a fixed switching frequency of 1MHz and is housed in a 16-SSOP surface-mount package. The component supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Integrates a synchronous step-up DC-DC converter with a linear LDO for combined power regulation
• Enables efficient power conversion through high-frequency synchronous switching operation
• Provides stable regulated outputs suitable for powering multiple circuit sections from a single source

Applications

• Portable electronic devices requiring dual voltage rails
• Battery-powered systems needing efficient step-up and linear regulation
• Embedded applications utilizing single-cell or multi-cell battery inputs

Procurement Notes

Verify the specific suffix 'EUE+' against official manufacturer documentation to confirm pinout compatibility and RoHS status. Confirm that the 16-SSOP package dimensions match your PCB footprint requirements. Check current availability status as this part may be subject to supply constraints or obsolescence notices from the manufacturer.

Selection Notes

Select this component when a design requires both a boosted voltage rail and a clean linear rail from a low-voltage source. Ensure the input voltage stays within the 0.7V to 5.5V operational window. Verify that the load currents do not exceed the 800mA boost limit or 500mA LDO limit under all thermal conditions.

Part Context

This part belongs to the MAX1765 family of dual-output PMICs designed for space-constrained applications. It replaces discrete solutions by integrating switching and linear regulators into one compact 16-pin SSOP package. The family targets efficiency improvements in portable electronics where board space and component count are critical constraints.

Replacement Considerations

The MAX1765EEE+ is listed as a direct substitute. Verify package equivalence between EUE+ and EEE+ variants before substitution.
