MAX1765EEE+T

Overview

The MAX1765EEE+T is a dual-output power management IC featuring a synchronous boost converter and a low-dropout linear regulator. It operates within an input voltage range of 0.7V to 5.5V. The boost output provides 2.5V to 5.5V at up to 800mA, while the LDO output offers 2.85V or adjustable voltage at 500mA. Operating at a fixed 1MHz switching frequency, it utilizes a 16-pin QSOP package and supports temperatures from -40°C to +85°C.

Feature Summary

Integrates a synchronous step-up DC-DC converter with a separate low-noise LDO for combined power efficiency and clean analog supply.
Supports wide input voltage ranges starting as low as 0.7V, enabling operation from single-cell lithium batteries.
Features a compact 16-pin QSOP footprint designed for space-constrained portable electronic applications.

Applications

Portable devices requiring simultaneous high-current digital power and low-noise analog rails
Battery-powered systems utilizing single-cell lithium-ion or lithium-polymer sources
Handheld instruments needing efficient voltage boosting alongside stable linear regulation

Procurement Notes

Verify component authenticity through authorized distributors due to discontinuation status. Confirm RoHS compliance requirements as standard versions may differ from lead-free variants. Validate package integrity upon receipt. Ensure storage conditions meet moisture sensitivity level specifications before reflow soldering processes.

Selection Notes

Select this component when system architecture demands both high-efficiency boosting and precise linear regulation in a single package. Evaluate thermal performance under maximum load conditions. Consider external component selection for stability at the specified switching frequency. Verify that input voltage profiles align with the minimum operating threshold.

Part Context

This device belongs to the Maxim Integrated PMIC family designed for mobile electronics. It consolidates multiple power stages into one solution, reducing board area compared to discrete implementations. The series targets applications where power density and noise isolation between digital and analog domains are critical design constraints.
