MAX16922ATPC/V+

Overview

The MAX16922ATPC/V+ is an automotive-grade power management IC featuring dual 2.2MHz step-down DC-DC converters, two low-dropout regulators, and a reset controller. It operates within a 3.7V to 28V input range and supports output currents of up to 1.2A for buck channels and 300mA for LDOs. The device provides four outputs with fixed voltages including 1V, 2.7V, 3.3V, and 5V. It is qualified under AEC-Q100 standards and functions reliably between -40°C and +125°C in a 20-pin TQFN package.

Feature Summary

• Integrates dual high-frequency buck converters and dual LDOs for efficient multi-rail power distribution
• Includes active-low reset functionality to ensure system reliability in automotive environments
• Automotive qualification ensures robust performance across extended industrial temperature ranges

Applications

• Infotainment systems requiring multiple regulated voltage rails
