MPQ4488BGU-FD-AEC1-Z

Overview

The MPQ4488BGU-FD-AEC1-Z is a three-output synchronous buck switching voltage regulator manufactured by Monolithic Power Systems. Designed for automotive applications, it operates within an input voltage range of 6 V to 36 V and delivers up to 6 A per channel. The device integrates three independent regulators with fixed output voltages of 5.1 V, 5.17 V, and 5.3 V. It features a high switching frequency of 2.2 MHz and low quiescent current of 1 mA. Packaged in a QFN-26 format, it supports operation from -40°C to +125°C and holds AEC-Q100 qualification.

Feature Summary

Integrates three independent synchronous buck converters for multi-rail power distribution
Supports wide input voltage ranges suitable for automotive load dump conditions
High switching frequency enables the use of compact external passive components
Qualified for automotive reliability standards with extended temperature coverage

Applications

Automotive infotainment systems requiring multiple regulated rails
Digital cockpit modules and instrument clusters
Advanced driver assistance system (ADAS) power distribution units
Telematics control units and gateway modules

Procurement Notes

Verify component authenticity through authorized MPS distributors or certified partners. Confirm the specific suffix FD indicates the correct pinout configuration for your PCB layout. Ensure compliance with RoHS directives and automotive quality standards before integration into production designs.

Selection Notes

Select this component when designing systems requiring three distinct voltage rails from a single controller. It is appropriate for applications needing high current density and wide input voltage tolerance. Consider thermal management requirements due to the integrated nature of the three channels within the QFN package.
