MPQ7920GRM-0003-AEC1-Z

Overview

The MPQ7920GRM-0003-AEC1-Z is a 5V PMIC featuring nine outputs: four synchronous buck converters and five LDOs. It operates within a 2.7V to 5.5V supply range at a 2.2MHz switching frequency. The device provides three programmable buck outputs (0.4V–3.5875V, 4.5A) and one fixed 2A output. It includes five LDOs with specific current ratings of 2A, 2.5A, 4.5A, and two 4A variants. Designed for automotive environments, it supports -40°C to 125°C junction temperatures and utilizes a 26-QFN (3.5x4.5mm) package.

Feature Summary

• Integrates four synchronous buck regulators and five low-dropout linear regulators in a single compact package.
• Features high-current capability with up to 4.5A per channel across multiple output stages.
• Includes programmable voltage settings on select buck channels for flexible power rail configuration.
• Complies with AEC-Q100 standards for reliable operation in demanding automotive thermal conditions.

Applications

• Automotive infotainment systems requiring multi-rail power distribution
• Digital cockpit modules needing synchronized power sequencing
• ADAS sensor processing units requiring stable voltage regulation

Procurement Notes

Verify the suffix 'Z' against official Monolithic Power Systems documentation to confirm lead-free status or RoHS compliance specifics. Ensure the ordering part number matches the exact tape-and-reel quantity specified in the manufacturer's datasheet. Cross-reference the AEC-Q100 qualification grade to validate automotive suitability for your specific application requirements.

Selection Notes

Select this component when designing automotive electronics that require a consolidated solution for multiple power rails from a 5V source. It is suitable for applications needing high peak currents up to 4.5A alongside precise LDO regulation. Consider the 26-QFN footprint constraints and thermal dissipation capabilities relative to your PCB layout and ambient operating temperature limits.

Part Context

This part belongs to the MPQ7920 family of automotive-grade power management ICs. It serves as an integrated solution for complex power architectures, replacing discrete regulator combinations. The GRM suffix indicates the specific package type and pinout configuration used in modern compact automotive electronic control units.

Replacement Considerations

Consult MPS documentation for direct substitutes such as MPQ7920GRM-0003-AEC1-P. Verify functional equivalence regarding output configurations and electrical parameters before implementation.
