MAX16922ATPK/V+

Overview

The MAX16922ATPK/V+ is an automotive-grade PMIC featuring dual 2.2MHz step-down DC-DC converters, two LDOs, and an active-low 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 regulated outputs at 1V, 2.7V, 3.3V, and 5V with -0.2% load regulation. Packaged in a 20-pin TQFN-EP, it functions between -40°C and +125°C.

Feature Summary

• Integrates dual high-frequency buck converters and dual low-dropout regulators for compact power design
• Includes an active-low reset generator for system supervision and fault protection
• Maintains voltage regulation during low-input conditions such as cold-crank events

Applications

• Automotive infotainment systems requiring multi-rail power sequencing
• Telematics control units needing robust transient response
• Body electronics modules operating under wide input voltage variations

Procurement Notes

This component is officially listed as obsolete by the manufacturer. Availability is restricted or limited, often requiring special factory orders. Verify current stock status with authorized distributors before finalizing designs. Consider lifecycle management strategies due to end-of-life status.

Selection Notes

Select this part when designing automotive applications requiring integrated buck and LDO rails in a small footprint. Ensure input voltage ranges from 3.7V to 28V align with system requirements. Verify thermal performance within the TQFN-EP package for the intended ambient temperature range.

Part Context

Part of the MAX16922 family of automotive PMICs designed for space-constrained vehicle electronics. It consolidates multiple power stages into a single solution, reducing bill of materials and board area compared to discrete regulator implementations.

Replacement Considerations

No direct public substitute part numbers are confirmed in official documentation. Due to the obsolete status, alternative components must be evaluated based on pin compatibility, electrical specifications, and automotive qualification standards.
