MAX77681AEWV+

Overview

The MAX77681AEWV+ is an ultra-low power PMIC from the MAX7768x series, featuring a SIMO topology with three outputs. It operates within an input voltage range of 2.7 V to 5.5 V and delivers up to 300 mA output current. The device supports adjustable output voltages from 800 mV to 5.25 V, with a quiescent current of 37.5 uA. It functions between -40°C and +85°C in a WLP-30 package.

Feature Summary

• Integrates three independent LDO regulators into a single compact package for efficient space-constrained designs.
• Utilizes Switched Inductor Multiple Output (SIMO) architecture to minimize external component count and reduce overall system footprint.
• Provides ultra-low quiescent current operation to extend battery life in portable applications.

Applications

• Portable consumer electronics requiring multi-rail power management
• Wearable devices with strict size and power constraints
• IoT sensors and modules

Procurement Notes

Verify availability status as supply may be limited or subject to factory special orders. Confirm RoHS compliance details through official documentation before integration. Ensure the WLP-30 package compatibility with your PCB layout tools. Check for any specific ordering suffix requirements that might affect function or packaging.

Selection Notes

Select this component when a low-pin-count solution is required for multiple voltage rails. The SIMO topology offers cost and space advantages over discrete regulators. Verify that the 300 mA total current capability meets the load requirements of all connected subsystems. Consider the thermal performance within the small WLP-30 package under maximum load conditions.

Part Context

This part belongs to the MAX7768x family of ultra-low power PMICs designed for mobile and wearable applications. It shares architectural similarities with the MAX77680 but offers specific output configurations tailored for compact systems. The series emphasizes minimal external components and high efficiency in a tiny form factor.

FAQ

What is the maximum output current for the MAX77681AEWV+?

The device provides a combined output current capability of 300 mA across its three integrated regulators.

Does the MAX77681AEWV+ include a buck converter?

No, it utilizes a SIMO (Switched Inductor Multiple Output) topology consisting of three LDOs, not a traditional buck converter.
