MPQ4488TGU-AEC1-P

Overview

The MPQ4488TGU-AEC1-P is a Monolithic Power Systems synchronous step-down converter featuring three independent buck channels. It supports an input voltage range of 6 V to 36 V and delivers up to 6 A per channel, providing combined output currents of 5.1 V, 5.17 V, or 5.3 V. The device operates with a fixed switching frequency of 2.2 MHz and maintains a quiescent current of 1 mA. Designed for automotive environments, it is qualified under AEC-Q100 standards and functions within a temperature range of -40°C to +125°C. Packaged in a QFN-26 format, this component integrates protection mechanisms suitable for high-reliability applications.

Procurement Notes

Verify the specific suffix against official MPS documentation to confirm package type and tape/reel specifications. Confirm that the AEC-Q100 qualification aligns with your target automotive grade requirements. Check for any design-not-recommended notices associated with this specific part number variant before finalizing procurement plans.

Selection Notes

Select this component when designing systems requiring multiple isolated low-voltage rails from a single high-voltage source. Ensure the thermal design accommodates the heat dissipation characteristics of the QFN-26 package under maximum load conditions. Verify that the 2.2 MHz switching frequency does not interfere with sensitive RF circuits in the application environment.

Part Context
