MPQ4276AGU-AEC1-P

Overview

The MPQ4276AGU-AEC1-P is a synchronous buck converter from Monolithic Power Systems, designed for automotive applications with AEC-Q100 qualification. It operates within an input voltage range of 6 V to 36 V and delivers up to 6 A output current. The device features a configurable switching frequency between 200 kHz and 2.2 MHz, allowing optimization for efficiency or component size. It includes dual USB charging ports and supports PFM mode under light loads to minimize static current consumption, which is specified at 800 uA. The maximum operating temperature reaches +125 C, housed in a QFN-26 package.

Feature Summary

• Integrated dual USB charging ports supporting automotive fast-charging protocols
• Configurable switching frequency range for flexible design optimization
• PFM mode operation under light loads to enhance energy efficiency
• Automotive-grade reliability certified to AEC-Q100 standards

Applications

• Automotive infotainment systems requiring stable power delivery
• Digital cockpit modules and instrument clusters
• Vehicle telematics units and connectivity modules
• ADAS sensor processing power supplies

Procurement Notes

Verify the specific suffix 'P' indicates reel packaging when confirming order details against official datasheets. Ensure the component meets AEC-Q100 Grade requirements for your target automotive environment. Cross-reference the QFN-26 footprint dimensions with your PCB layout guidelines before finalizing procurement specifications.

Selection Notes

Select this component when a 6 A output capability is required for 12 V or 24 V automotive bus architectures. The wide input voltage range accommodates cold crank conditions typical in vehicle electrical systems. Consider the configurable frequency feature if electromagnetic interference (EMI) constraints necessitate shifting the switching noise away from sensitive receiver bands.

Part Context

This part belongs to the MPQ4276 family of high-efficiency synchronous step-down converters. It shares the QFN-26 package topology with other MPS automotive regulators but is distinctively configured for dual USB port integration. The AEC1 suffix denotes automotive grade qualification, differentiating it from commercial variants that may lack extended temperature or reliability testing.

Replacement Considerations

MPQ4276AGU-AEC1-Z serves as a direct alternative with identical electrical characteristics but utilizes tape-and-reel packaging instead of cut-tape.
