MAXI15004AAUE/V+T

High-Efficiency Automotive Buck Regulator for Wide VIN Power Systems

Product Description

Product Overview

The MAXI15004AAUE/V+T is an automotive-qualified high-efficiency synchronous step-down (buck) DC/DC converter designed for powering sensitive electronics from wide input voltage sources such as automotive batteries. It integrates internal high-side and low-side MOSFETs, enabling compact designs with minimal external components. With excellent efficiency across load conditions and robust protection features, the device is well suited for infotainment systems, ADAS modules, instrument clusters, and other in-vehicle power rails.
