Overview
The MPQ4228GRE-Q-AEC1-P is a Monolithic Power Systems synchronous step-down converter designed for automotive applications. It features an integrated USB charging port supporting CDP and Type-C standards with 5V at 3A DFP mode. The device operates with an input voltage range of 4.2 V to 36 V and delivers up to 3 A output current. It utilizes a fixed 2.2 MHz switching frequency and includes shutdown functionality. Qualified under AEC-Q100, it functions within a temperature range of -40°C to +150°C TJ in a QFN-22 package.
Feature Summary
- Integrated USB charging port supporting CDP and Type-C protocols
- Automotive-grade AEC-Q100 qualification
- Synchronous buck topology with high efficiency
Applications
- Automotive infotainment systems
- Vehicle telematics units
- Digital cockpit displays
Procurement Notes
Verify the specific suffix 'Q' against official MPS documentation, as standard listings typically use 'GRE-AEC1-P'. Confirm package type and thermal characteristics match design requirements. Ensure compatibility with automotive supply rail transients. Check for updated datasheet revisions regarding electrical parameters.
Selection Notes
Select this component for designs requiring integrated USB power delivery alongside main system regulation. The fixed 2.2 MHz frequency allows for smaller passive components compared to lower-frequency alternatives. Verify that the 36 V maximum input rating aligns with the vehicle's cold crank and load dump specifications.
Part Context
This part belongs to the MPQ4228 series of automotive-grade DC-DC converters. It shares core architecture with other members but is distinguished by its integrated USB controller capabilities. The series targets high-current applications in modern vehicles requiring standardized charging interfaces.
Replacement Considerations
MPQ4228GRE-AEC1-Z serves as a reel-pack alternative within the same functional family.
