MAX16922ATPI/V+T

Overview

The MAX16922ATPI/V+T is a specialized power management IC (PMIC) featuring two 2.2MHz synchronous step-down DC-DC converters, two low-dropout linear regulators (LDOs), and an active-low reset controller. It operates within an input voltage range of 3.7V to 28V. The device provides four outputs with current capabilities of up to 1.2A for the buck converters and 300mA for the LDOs. Packaged in a 20-pin TQFN with an exposed pad, it supports automotive AEC-Q100 qualification and functions reliably across temperatures from -40°C to +125°C.

Feature Summary

• Integrates dual high-frequency buck converters and dual LDOs for compact multi-rail power solutions
• Includes an active-low reset controller for system supervision
• Designed for automotive and medical applications with robust operating specifications

Applications

• Automotive infotainment systems
• Medical instrumentation power supplies
• Industrial control modules requiring multiple regulated rails

Procurement Notes

Verify component authenticity through authorized channels due to limited supply status. Confirm package marking and lot traceability against official datasheet specifications. Ensure storage conditions comply with moisture sensitivity levels prior to assembly. Cross-reference ordering information with manufacturer documentation to validate suffix designations.

Selection Notes

Select this PMIC when designing space-constrained boards requiring integrated buck and LDO regulation. Verify that the 28V maximum input voltage aligns with the system bus. Ensure thermal management strategies accommodate the TQFN-EP-20 package dissipation requirements under full load conditions.

Part Context

This component belongs to the MAX16922 family of automotive-grade power management ICs. It consolidates multiple power stages into a single solution, reducing bill-of-materials count compared to discrete regulator implementations. The series targets applications demanding high reliability and strict size constraints.

Replacement Considerations
