MPQ4488BGU-FD-AEC1-P

Overview

The MPQ4488BGU-FD-AEC1-P is a Monolithic Power Systems buck converter featuring three independent outputs with a total current capacity of 6 A. It operates within an input voltage range of 6 V to 36 V and delivers fixed output voltages of 5.1 V, 5.17 V, and 5.3 V. The device supports a programmable switching frequency from 250 kHz to 2.2 MHz and incorporates spread spectrum technology for EMI reduction. Qualified under AEC-Q100 standards, it functions reliably between -40°C and +125°C in a QFN-26 package.

Feature Summary

• Dual USB charging ports integrated for automotive applications
• Programmable switching frequency with spread spectrum modulation
• AEC-Q100 qualified for automotive reliability

Applications

• Automotive infotainment systems
• Digital cockpit displays
• ADAS sensor power supplies

Procurement Notes

Verify the specific suffix FD against official MPS documentation to confirm functional differences from standard variants. Ensure the AEC-Q100 qualification status matches your project's automotive grade requirements. Confirm the QFN-26 package dimensions align with your PCB layout constraints before finalizing procurement.

Selection Notes

Select this component when designing for automotive environments requiring multiple regulated rails from a single high-voltage source. The integrated dual USB ports simplify interface design for mobile devices. Consider the programmable frequency range to optimize efficiency versus EMI performance based on system noise sensitivity.

Part Context

This part belongs to the MPQ4488 series of multi-output DC-DC converters designed specifically for automotive use. It consolidates power management functions typically requiring separate regulators into a single compact solution. The series emphasizes high integration and robustness for demanding vehicle electronics.

Replacement Considerations

MPS recommends MPQ4488BGU-AEC1-Z or MPQ4488BGU-FD-AEC1-Z for new designs.
