MAX16922AUPA/V+T

Overview

The MAX16922AUPA/V+T is an automotive-grade power management integrated circuit (PMIC) designed for TFT-LCD applications. It integrates two synchronous step-down DC-DC converters, two low-dropout (LDO) regulators, and an active-low reset controller within a single package. The device operates from an input voltage range of 3.7V to 28V and supports a switching frequency of 2.2MHz. It provides four regulated outputs with specific current capabilities: the buck converters deliver up to 1.2A and 600mA, while the LDOs provide 300mA each. Standard output voltages include 1V, 2.7V, 3.3V, and 5V. The component is housed in a 20-TSSOP-EP package and is qualified to AEC-Q100 standards for operation between -40°C and +125°C.

Feature Summary

• Integrates dual synchronous buck converters and dual LDO regulators for comprehensive power rail generation
• Includes an active-low reset controller to ensure system stability during power transitions
• Automotive qualification compliant with AEC-Q100 standards for reliable vehicle operation

Applications

• Power supply architecture for automotive TFT-LCD displays
• General purpose automotive electronic systems requiring multiple regulated rails
• Infotainment and instrument cluster power management modules

Procurement Notes

This component is officially listed as obsolete by Analog Devices/Maxim Integrated. Distribution channels indicate restricted availability or non-supply status. Verify end-of-life documentation and obsolescence notices directly with the manufacturer before finalizing design-in decisions. Sourcing may require checking secondary markets or authorized distributors for remaining stock, though no guaranteed inventory exists.

Selection Notes

Select this part when designing for automotive LCD panels requiring a compact solution with integrated buck and LDO stages. Ensure the input voltage range of 3.7V to 28V matches the vehicle's battery profile. Consider the 2.2MHz switching frequency for passive component size optimization. Verify that the thermal performance of the 20-TSSOP-EP package meets the application's heat dissipation requirements under maximum load conditions.

Part Context

The MAX16922 belongs to the Maxim Integrated automotive PMIC family tailored for display drivers. It consolidates functions typically spread across discrete components, reducing board space and assembly complexity. The device is specifically engineered to meet the stringent reliability and environmental standards required for modern automotive infotainment and instrumentation systems.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. As the part is obsolete, engineers must evaluate alternative PMICs from the same manufacturer or competitors that offer similar pin compatibility and electrical specifications.
