MAX25249ATPK/VY+

Overview

The MAX25249ATPC/VY+ is a high-voltage, four-output PMIC designed for automotive camera applications. It integrates three synchronous step-down DC-DC converters and one low-noise LDO. The device operates from an input voltage range of 4.5V to 36V. Output 1 provides up to 1A at 3V to 4V. Outputs 2 and 3 deliver up to 1.2A each with adjustable voltages from 0.8V to 3.9875V. Output 4 is a dedicated LDO for image sensor power. The IC features a fixed 2.2MHz switching frequency, ±1.5% output voltage accuracy, and overvoltage/undervoltage monitoring. It is housed in a 20-WETQFN package and meets AEC-Q100 and ASIL-B standards.
