MAX20025S Automotive Step-Down DC-DC Power Supply IC for ADAS & Charging Systems

MAX20025S is a high-performance synchronous step-down DC-DC converter optimized for next-generation automotive power architectures.

This IC is designed to deliver efficient and stable power to advanced driver-assistance systems (ADAS) and electric vehicle charging modules.

It integrates high-side and low-side switching elements to support high-efficiency power conversion, minimizing heat dissipation and improving system reliability.

The wide input voltage range ensures seamless operation during engine start-stop and cold-crank conditions, making it suitable for harsh automotive environments.

Internal loop compensation, soft-start, and frequency foldback features simplify external circuitry and reduce overall design complexity.

The device includes comprehensive protection mechanisms such as overcurrent, overtemperature, and undervoltage lockout to safeguard sensitive downstream electronics.

A compact thermally-enhanced package allows for high-density PCB layouts common in modern vehicle control units.

This AEC-Q100 qualified IC is an ideal building block for powering domain controllers, sensor clusters, and high-voltage battery management interfaces.
