MAX16922ATPD/V+T

Overview

The MAX16922ATPD/V+T is a power management IC featuring two 2.2MHz synchronous buck converters and two low-dropout regulators. It supports an input voltage range of 3.7V to 28V with four outputs providing 1V, 2.7V, 3.3V, and 5V at currents up to 1.2A. The device operates between -40°C and +125°C, offers ±0.2% load regulation, and is housed in a 20-lead TQFN package.

Feature Summary

• Integrates dual step-down DC-DC converters and dual LDOs for comprehensive power distribution
• Supports wide automotive input voltage ranges from 3.7V to 28V
• Features high switching frequency of 2.2MHz to minimize external component size

Applications

• Automotive infotainment systems
• Telematics control units
• Body control modules
• ADAS sensor power supplies

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing. Confirm AEC-Q100 qualification status for automotive reliability requirements. Ensure the 20-TQFN footprint matches the design layout. Check current supply chain availability as this series may have limited stock or obsolescence risks.

Selection Notes

Select this component for applications requiring multiple regulated rails from a fluctuating automotive bus. The dual buck topology handles higher current loads while LDOs provide clean power for sensitive analog circuits. Consider thermal performance in the TQFN package for dense PCB layouts.

Part Context

This part belongs to the MAX16922 family of integrated power management solutions designed for harsh environments. It consolidates multiple voltage conversion stages into a single compact solution, reducing board space compared to discrete regulator designs.
