MAX16922ATPO/V+T

Overview

The MAX16922ATPO/V+T is a power management IC featuring two 2.2MHz synchronous buck converters, dual LDOs, and an active-low reset controller. It supports input voltages from 3.7V to 28V with four outputs delivering up to 1.2A, 600mA, 450mA, and 600mA respectively. Fixed output options include 1V, 2.7V, 3.3V, and 5V. The device operates between -40°C and +125°C, offers 0.2% load regulation, and is AEC-Q100 qualified for automotive use in a TQFN-EP package.

Feature Summary

• Integrates dual high-frequency step-down DC-DC converters with dual low-dropout regulators and a reset monitor
• Provides comprehensive protection mechanisms including thermal shutdown, current limiting, and undervoltage lockout
• Features adjustable switching frequency synchronization and precise voltage monitoring for system reliability

Applications

• Automotive infotainment systems requiring multi-rail power distribution
• Telematics control units needing compact power solutions
• Body electronics modules demanding high efficiency and thermal performance
• Industrial control systems operating in harsh environments

Procurement Notes

Verify the specific suffix 'V+T' indicates tape-and-reel packaging configuration distinct from tube variants. Confirm AEC-Q100 qualification status matches project requirements. Check for obsolescence notices as Maxim Integrated products may transition through Analog Devices lifecycle stages. Ensure compatibility with existing board layouts regarding the TQFN-EP thermal pad connection.

Selection Notes

Select this component when designing systems requiring integrated buck, LDO, and reset functions in a minimal footprint. Consider the 2.2MHz switching frequency for smaller passive component sizes compared to lower-frequency alternatives. Evaluate thermal dissipation capabilities given the high integration density in the 5mm x 5mm package. Verify input voltage range suitability against the specific application's supply characteristics.
