MAX16922ATPF/V+

Overview

The MAX16922ATPF/V+ is a power management integrated circuit featuring two 2.2 MHz synchronous step-down DC-DC converters, two low-dropout linear regulators, and an active-low reset controller. It operates within an input voltage range of 3.7 V to 28 V. The device provides four outputs with specific current capabilities: the buck converters deliver up to 1.2 A and 600 mA, while the LDOs provide 450 mA each. It utilizes a TQFN-EP-20 package and supports automotive qualification under AEC-Q100 standards.

Feature Summary

• Integrates dual high-frequency buck converters with dual LDOs and a reset supervisor in a single compact package.
• Supports wide input voltage ranges suitable for automotive battery systems and industrial applications.
• Features precise load regulation and thermal protection mechanisms for stable operation.

Applications

• Automotive infotainment and telematics systems
• Industrial control modules requiring multi-rail power distribution
• Embedded computing platforms needing efficient voltage conversion

Procurement Notes

Verify component authenticity through authorized channels due to potential counterfeit risks. Confirm package marking and datasheet revisions match the specific order code. Check for obsolescence status as availability may be limited. Ensure environmental compliance documentation aligns with project requirements before finalizing procurement decisions.

Selection Notes

Select this component when designing systems requiring multiple regulated rails from a single wide-input source. Evaluate thermal performance within the TQFN-EP-20 footprint against system constraints. Compare switching frequency requirements against electromagnetic interference limits. Verify that output current demands do not exceed the specified ratings for each regulator channel.

Part Context

This part belongs to the MAX16922 series of integrated power management solutions designed for space-constrained applications. It consolidates multiple power stages into one device, reducing board area compared to discrete solutions. The series targets markets demanding high efficiency and reliability in harsh environments.

Replacement Considerations

Direct substitutes include other variants within the MAX16922 family such as MAX16922ATPK/V+ or MAX16922ATPE/V+, which share identical electrical characteristics but differ in packaging or reel specifications. Cross-reference pinouts and thermal pad connections before substitution.
