MPQ4488TGU-AEC1-Z

Overview

The MPQ4488TGU-AEC1-Z is a Monolithic Power Systems automotive-grade synchronous buck converter featuring three independent output channels. It operates within an input voltage range of 6 V to 36 V and delivers up to 6 A per channel. The device utilizes a fixed 2.2 MHz switching frequency and provides precise output voltages of 5.1 V, 5.17 V, or 5.3 V. Packaged in a QFN-26 format, it supports surface-mount installation and functions reliably across a temperature range of -40°C to +125°C. Designed for high efficiency, the regulator maintains a low static current of 1 mA.

Feature Summary

• Three independent synchronous buck channels provide flexible multi-rail power distribution
• Automotive qualification ensures reliability under harsh environmental conditions
• High-frequency operation enables compact external component sizing

Applications

• Automotive infotainment systems requiring multiple regulated rails
• Digital cockpit modules with mixed voltage logic requirements
• ADAS sensor processing units needing stable power delivery

Procurement Notes

Verify the specific suffix configuration against the official datasheet to ensure compatibility with target design parameters. Confirm that the QFN-26 package dimensions align with PCB layout constraints. Check for any recent engineering change notices that may affect pinout or thermal characteristics before finalizing procurement specifications.

Selection Notes

Select this component when designing automotive electronics requiring three isolated outputs from a single input source. Ensure the application demands a switching frequency near 2.2 MHz to optimize inductor size. Verify that the load current does not exceed the 6 A per channel limit under maximum operating temperatures.

Part Context

This part belongs to the MPQ4488T series of automotive power management integrated circuits. It is designed specifically for applications requiring high density and robust performance in vehicle environments. The series emphasizes integration and efficiency to reduce overall system footprint while maintaining strict automotive quality standards.

Replacement Considerations

Official documentation recommends MPQ4488BGU-AEC1Z or MPQ4488BGU-FD-AEC1Z as preferred alternatives for new designs. These substitutes may offer updated features or improved availability compared to the current model.
