MPQ2166GDE-AEC1-P

Voltage Regulators - DC DC Switching Regulators Overview

The MPQ2166GDE-AEC1-P is an automotive-grade dual synchronous step-down converter manufactured by Monolithic Power Systems. It operates within a 2.7 V to 6 V input voltage range and delivers up to 3 A of output current per channel, or supports flexible configurations such as 2 A/2 A or 3 A/1 A. The device features a fixed 3 MHz switching frequency and maintains a low quiescent current of 60 uA. Output voltages are adjustable from 600 mV to 5.5 V. It is qualified under AEC-Q100 standards for reliability in harsh environments and functions reliably across a temperature range of -40°C to +125°C.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'GDE' against official datasheets to confirm package type and pinout compatibility before integration. Ensure that the selected variant meets the required thermal dissipation specifications for the intended enclosure. Cross-reference the AEC-Q100 certification documents to validate compliance with automotive quality standards. Confirm that the operating temperature range aligns with the environmental conditions of the final application.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when dual isolated outputs are required within a compact footprint for automotive applications. The 3 MHz frequency allows for smaller external passive components compared to lower-frequency alternatives. Consider the 60 uA quiescent current for battery efficiency in standby modes. Evaluate the thermal performance of the QFN-18 package relative to the expected load current and ambient temperature constraints.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the MPQ2166G series of dual synchronous buck converters designed specifically for automotive markets. It shares architectural similarities with industrial grade variants but includes enhanced testing and documentation for automotive reliability.
