MPQ4488BGU-AEC1-Z

Overview

The MPQ4488BGU-AEC1-Z is a Monolithic Power Systems buck converter featuring three independent outputs with fixed voltages of 5.1 V, 5.17 V, and 5.3 V. It supports up to 6 A output current within a 6 V to 36 V input range. The device includes programmable switching frequency from 250 kHz to 2.2 MHz and spread spectrum modulation. Qualified under AEC-Q100 standards, it operates between -40°C and +125°C in a QFN-26 package.

Feature Summary

• Supports dual USB charging ports via integrated features
• Includes spread spectrum modulation for EMI reduction
• Features programmable switching frequency for optimization

Applications

• Automotive infotainment systems
• Digital cockpit modules
• Telematics control units

Procurement Notes

Verify the specific suffix 'FD' or absence thereof against official MPS documentation, as variants like MPQ4488BGU-FD-AEC1-P exist. Confirm AEC-Q100 qualification status directly from the datasheet. Ensure the QFN-26 package matches your PCB footprint requirements before finalizing procurement orders.

Selection Notes

Select this component when designing automotive power architectures requiring multiple regulated rails from a single controller. The integrated USB charging port support simplifies interface design. Verify that the 6 A total current capability meets the combined load requirements of all three output channels simultaneously.

Part Context

This part belongs to the MPQ4488 series of high-efficiency step-down converters designed for automotive applications. It integrates multiple LDO-like outputs into a synchronous buck architecture, reducing external component count compared to discrete solutions.

Replacement Considerations

Official recommendations suggest MPQ4488BGU-AEC1-Z or MPQ4488BGU-FD-AEC1-Z as alternatives. Verify pinout compatibility and thermal performance before substitution.
