MAX1765EEE+

Overview

The MAX1765EEE+ is a dual-output power management IC combining a synchronous boost converter and a low-dropout linear regulator. It operates from an input voltage range of 0.7V to 5.5V. The first output provides 2.5V to 5.5V at up to 800mA, while the second offers 2.85V or adjustable voltage at 500mA. Switching frequency is fixed at 1MHz. The device is housed in a 16-QSOP package and supports operation between -40°C and +85°C.

Feature Summary

Integrates a synchronous step-up DC-DC converter with a linear LDO for efficient multi-rail power generation.
Supports ultra-low input voltages starting from 0.7V, enabling operation from single-cell lithium sources.
Features a compact surface-mount QSOP package suitable for space-constrained portable designs.

Applications

Portable electronic devices requiring multiple regulated voltage rails
Battery-powered systems utilizing single-cell lithium-ion or lithium-polymer sources
Embedded applications needing combined switching and linear regulation

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status as original variants may differ. Check current lifecycle status since the base part is obsolete; ensure the specific suffix matches design requirements. Validate package integrity upon receipt.

Selection Notes

Select this component when designing circuits that require both boosted and regulated lower voltages from a single low-voltage source. Ensure the load currents remain within the 800mA and 500mA limits respectively. Consider thermal dissipation in the QSOP package under high load conditions.

Part Context

This part belongs to the MAX1765 family of mixed-signal power management solutions. It is designed to simplify power architecture by integrating two distinct regulation topologies into a single chip, reducing component count compared to discrete solutions.
