MAX16922ATPJ/V+T

Overview

The MAX16922ATPJ/V+T is a power management IC featuring two 2.2 MHz synchronous step-down DC-DC converters and two low-dropout (LDO) regulators. It supports an input voltage range of 3.7 V to 28 V with outputs at 1 V, 2.7 V, 3.3 V, and 5 V. The buck converters provide up to 1.2 A current, while LDOs deliver up to 450 mA. Packaged in a 20-WQFN exposed pad, it operates from -40°C to +125°C and holds AEC-Q100 automotive qualification.

Feature Summary

• Integrates dual high-frequency buck converters and dual LDOs for compact system design
• Supports wide input voltage range suitable for battery and bus-powered applications
• Automotive-grade reliability with AEC-Q100 certification
• Includes active-low reset generator for system supervision

Applications

• Automotive infotainment systems
• Telematics control units
• Body control modules
• Industrial sensor hubs

Procurement Notes

Verify the suffix 'V+T' indicates tape-and-reel packaging. Confirm the 'A' grade denotes extended temperature range. Check for obsolescence notices as this family has faced discontinuation events. Ensure the exposed pad thermal connection matches your PCB layout requirements.

Selection Notes

Select this component when space constraints require integrated switching and linear regulation. The 2.2 MHz frequency allows smaller passive components. Verify that the combined output current requirements fit within the device's thermal limits. Consider the TSSOP alternative if QFN soldering capabilities are limited.

Part Context

This part belongs to the MAX16922 family of highly integrated PMICs designed for automotive and industrial use. It consolidates multiple power rails into a single solution, reducing bill-of-materials count. The series is known for its robustness in electrically noisy environments typical of vehicle chassis applications.

Replacement Considerations

MAX16922ATPA/V+T offers similar functionality in a WQFN package. MAX16922ATPK/V+ provides the same features in a TQFN footprint. Cross-reference pinouts and thermal pads before substitution.
