MPQ4272GVE-0001-AEC1-P

Overview

The MPQ4272GVE-0001-AEC1-P is a dual synchronous buck converter from Monolithic Power Systems, designed for automotive power delivery. It features an I2C interface and holds AEC-Q100 qualification. The device supports an input voltage range up to 36V, with each channel delivering 3A output current. Output voltages are adjustable from 1V to 21V. Key electrical parameters include a 2.1MHz switching frequency, 300µA quiescent current, and operation across a temperature range of -40°C to +150°C. The component is housed in a QFN-21 package.

Feature Summary

• Dual-channel architecture providing independent power rails via integrated synchronous buck converters
• Digital control capability through an I2C interface for configuration and monitoring
• Automotive-grade reliability certified under the AEC-Q100 standard for harsh environments

Applications

• Automotive infotainment system power distribution
• Telematics unit voltage regulation
• Advanced driver assistance systems (ADAS) power management

Procurement Notes

Verify the specific suffix against official MPS documentation to confirm exact factory settings and revision levels. Ensure compatibility with automotive supply chain requirements by confirming AEC-Q100 certification status directly with the manufacturer or authorized distributors before integration into production designs.

Selection Notes

Select this component when designing systems requiring two isolated, digitally controllable power rails within a compact footprint. The high switching frequency allows for smaller external passive components, while the wide operating temperature range ensures stability in demanding automotive thermal conditions compared to industrial-grade alternatives.

Part Context

This part belongs to the MPQ4272 series of dual synchronous step-down converters. It is engineered specifically for automotive applications, distinguishing itself from general-purpose PMICs by its robust qualification standards and digital interface capabilities tailored for complex vehicle electronic architectures.

Replacement Considerations

Consult MPS official cross-reference lists for verified substitutes. Generic equivalents may lack the required AEC-Q100 certification or I2C digital control functionality.
