MAX25249ATPH/VY+

Overview

The MAX25249ATPH/VY+ is a high-voltage, ASIL-B certified camera power management integrated circuit (PMIC) manufactured by Analog Devices Inc. under the Maxim Integrated brand. It features four outputs: three synchronous buck converters and one low-dropout regulator (LDO). The device operates with an input voltage range of 4.5 V to 36 V. Output specifications include 1 A for Buck 1 (3 V to 4 V), and 1.2 A each for Buck 2 and Buck 3 (0.8 V to 3.9875 V). The LDO output supports up to 1 A. The switching frequency is fixed at 2.2 MHz. It is housed in a 20-WETQFN package measuring 3.5 mm x 3.5 mm.
