MPQ4488TGU-FD-AEC1-Z

Overview

The MPQ4488TGU-FD-AEC1-Z is a three-output USB voltage regulator IC from Monolithic Power Systems, designed for automotive applications. It operates within an input voltage range of 6 V to 36 V and features a QFN-26 (5x5) package. The device provides fixed output voltages of 5.1 V, 5.17 V, and 5.3 V. It supports switching frequencies configurable between 200 kHz and 2.5 MHz. The component is AEC-Q100 qualified and functions as a step-down converter suitable for high-reliability environments.

Feature Summary

Configurable switching frequency capability supporting operation from 200 kHz to 2.5 MHz
Three dedicated outputs optimized for USB voltage regulation requirements
Automotive-grade qualification ensuring reliability under harsh environmental conditions

Applications

Automotive infotainment systems requiring stable USB power delivery
Vehicle connectivity modules needing multiple regulated voltage rails
High-reliability automotive electronic control units with USB interfaces

Procurement Notes

Verify the specific suffix configuration against design requirements before procurement. Confirm that the fixed output voltages align with target load specifications. Ensure compatibility with the intended switching frequency range for EMI management. Check current availability status as supply levels may fluctuate. Validate package dimensions against PCB layout constraints prior to ordering.

Selection Notes

Select this component when multiple regulated outputs are required for USB-centric automotive designs. Consider the wide input voltage range for robustness against load dump events. Evaluate thermal performance within the QFN-26 package for the specific application environment. Compare against single-output alternatives if fewer rails are sufficient. Verify AEC-Q100 compliance meets project quality standards.

Part Context

This part belongs to the MPQ4488 series of special purpose regulators by Monolithic Power Systems. It is engineered specifically for automotive USB power distribution tasks. The device integrates synchronous buck converters to provide efficient voltage stepping. It shares family characteristics with other MPQ44xx series components but offers distinct multi-output capabilities tailored for complex system architectures.
