MAX77681AEWV+T

Overview

The MAX77681AEWV+T is a specialized power management integrated circuit (PMIC) designed for ultra-low power applications. It features a Single Inductor Multiple Output (SIMO) topology with three independent output channels. The device operates within an input voltage range of 2.7 V to 5.5 V and supports adjustable output voltages up to 5.25 V. Key electrical specifications include a quiescent current of 37.5 uA, an output current capability of 300 mA, and a maximum power dissipation of 1.632 W. It functions reliably across a temperature range of -40°C to +85°C and utilizes a WLP-30 package.

Feature Summary

• Integrates a SIMO buck-boost converter architecture to provide multiple regulated outputs from a single inductor.
• Optimized for ultra-low power consumption with minimal static current draw during operation.
• Supports shutdown functionality to further reduce power usage in standby modes.

Applications

• Ultra-low power portable electronic devices
• Battery-operated sensor nodes
• Wearable technology requiring compact power solutions

Procurement Notes

Verify the specific suffix 'T' indicates reel packaging when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure availability checks are performed as supply may be restricted or subject to factory special orders. Validate that the WLP-30 footprint matches the target PCB design constraints.

Selection Notes

Select this component when a multi-output solution is required without the area penalty of multiple inductors. The SIMO topology is suitable for loads that do not require simultaneous high-current demands on all rails. Consider the 300 mA total output limit and the 37.5 uA quiescent current against system power budgets. Verify compatibility with the 2.7 V to 5.5 V input range relative to the battery source.

Part Context

This part belongs to the MAX7768x series of PMICs from Analog Devices/Maxim Integrated. It shares architectural similarities with the MAX77680 but offers distinct configuration options within the same family. These components are engineered for space-constrained applications where efficiency and size are critical factors in system design.

Replacement Considerations

The MAX77680AEWV+ is a related variant within the same product family. Verify functional equivalence regarding output configurations and pinout compatibility before substitution. Consult official datasheets to confirm if specific ordering suffixes alter performance characteristics or packaging details.
