MAX20028BATJA/VY+T

Overview

The MAX20028BATJA/VY+T is a power management integrated circuit (PMIC) designed for automotive applications. It integrates three channels of DC-DC conversion within a compact package. The device features a high-voltage buck controller and dual 2.1MHz step-down converters. Output voltage ranges from 0.8V to 3.95V. It operates between -40°C and +125°C. The component holds AEC-Q100 qualification.

Feature Summary

• Integrates three power channels in a small footprint
• Includes one high-voltage buck controller
• Features dual 2.1MHz switching regulators
• Qualified for automotive environments

Applications

• Automotive infotainment systems
• Vehicle instrument clusters
• ADAS sensor power supplies

Procurement Notes

Verify the specific suffix VY+T against official Analog Devices documentation to confirm pinout and thermal pad configuration. Ensure the source provides valid RoHS compliance statements. Confirm availability status directly with authorized distributors as supply levels fluctuate. Validate that the received unit matches the exact part number to avoid functional mismatches in automotive circuits.

Selection Notes

Select this PMIC when space-constrained automotive designs require multiple regulated rails. It suits applications needing high-voltage input handling alongside low-noise outputs. Consider its 2.1MHz frequency for smaller external passive components. Verify thermal requirements match the TDFN or WQFN package capabilities for the target enclosure.

Part Context

This component belongs to Maxim Integrated's automotive PMIC portfolio, now under Analog Devices. It addresses the trend toward centralized power distribution in modern vehicles. The series replaces discrete regulator solutions to reduce board area and simplify design complexity for OEMs developing next-generation electronic control units.
