MAX16922AUPA/V+

Overview

The MAX16922AUPA/V+ is an automotive-grade power management IC featuring two 2.2MHz step-down DC-DC converters and two low-dropout (LDO) regulators. It operates within a 3.7V to 28V input range and supports output currents of up to 1.2A for the switching regulators and 600mA for the LDOs. The device provides four regulated outputs, including fixed voltages of 1V, 2.7V, 3.3V, and 5V. It is housed in a 20-TSSOP package with an exposed pad and is qualified to AEC-Q100 standards for operation between -40°C and +125°C.
