MAX25249ATPC/VY+T

Overview

The MAX25249ATPC/VY+T is a high-voltage, ASIL-B certified camera power management integrated circuit (PMIC) designed for automotive applications. It integrates four output regulators: three synchronous buck converters and one low-dropout linear regulator (LDO). The device operates within an input voltage range of 4.5V to 36V and supports a switching frequency of 2.2MHz. Output specifications include 1A at 3V-4V for the first channel, and 1.2A at 0.8V-3.9875V for channels two and three. It is housed in a 20-WETQFN package with wettable flanks.
