MPQ2166GRH-AEC1-Z

Voltage Regulators - DC DC Switching Regulators Overview

The MPQ2166GRH-AEC1-Z is an automotive-grade synchronous buck converter featuring dual adjustable outputs. It operates with an input voltage range of 2.7 V to 6 V and delivers up to 3 A total output current, configurable as 2 A/2 A or 3 A/1 A per channel. The device supports a fixed switching frequency of 3 MHz and maintains a low quiescent current of 60 uA. Output voltages are adjustable from 600 mV to 5.5 V. It includes power good indication and soft-start capabilities, housed in a QFN-18 package, and meets AEC-Q100 standards for operation between -40°C and +125°C.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix configuration against official Monolithic Power Systems documentation to ensure compatibility with required packaging and automotive grade specifications. Confirm that the QFN-18 footprint matches the target PCB layout constraints. Cross-reference the datasheet revision history to validate thermal performance parameters under intended load conditions before finalizing procurement orders.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when designing systems requiring dual isolated rails from a single 6V automotive source. The 3 MHz switching frequency allows for smaller passive components compared to lower-frequency alternatives. Ensure the application demands the specific 2A/2A or 3A/1A current sharing profile supported by this variant rather than higher-current single-output regulators.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the MPQ2166G series of high-efficiency DC-DC converters designed specifically for automotive environments. It complements other MPS solutions like the MP2162 for single-channel applications, offering increased integration for complex multi-rail requirements in modern vehicle electronics without sacrificing efficiency or thermal performance.
