MAX20031CATMD/V+T

Overview

The MAX20031CATMD/V+T is a specialized power management integrated circuit (PMIC) designed for complete front-end power supply applications. It integrates dual buck converters, a synchronous boost converter, and an LDO regulator within a single package. The device operates with a supply voltage range of 3.5V to 42V and supports an operating temperature range from -40°C to +125°C. It features a low quiescent current of 17µA and is housed in a 48-WFQFN exposed pad package.

Feature Summary

• Integrates dual buck, sync boost, and LDO regulators for comprehensive power management
• Supports wide input voltage range from 3.5V to 42V
• Features ultra-low quiescent current of 17µA for energy efficiency
• Rated for extended industrial operating temperatures up to 125°C

Applications

• Front-end power supply systems
• Industrial control units
• Automotive electronics requiring wide input voltage tolerance

Procurement Notes

Verify the exact suffix configuration against the manufacturer's official datasheet to ensure compatibility with specific thermal and electrical requirements. Confirm that the 48-WFQFN package dimensions align with your PCB footprint design. Check for any recent product change notices or lifecycle status updates directly from Analog Devices to ensure long-term availability and support.

Selection Notes

Select this component when a compact solution is needed to manage multiple voltage rails from a wide input range. The integration of buck, boost, and LDO functions reduces component count and board space. Ensure the application demands the specified 17µA quiescent current performance and can accommodate the thermal characteristics of the exposed pad QFN package under maximum load conditions.

Part Context

This part belongs to the Maxim Integrated line of specialized PMICs, now part of Analog Devices Inc. It is engineered to simplify power architecture by combining multiple conversion stages into one IC. This approach minimizes external components and improves system reliability compared to discrete solutions.

Replacement Considerations

Consult the official Analog Devices replacement matrix for verified substitutes. Cross-reference pinouts and electrical specifications carefully before considering alternative packages or series.
