Voltage Regulators - DC DC Switching Regulators datasheet and documents for MPQ4423GQ-Z

MPQ4423GQ-Z

Voltage Regulators - DC DC Switching Regulators Overview

The MPQ4423GQ-Z is an industrial-grade synchronous step-down converter from Monolithic Power Systems. It features a buck topology with a QFN-8 package, supporting SMD/SMT installation. The device accepts an input voltage range of 4 V to 30 V and delivers up to 3 A output current. Output voltage is adjustable from 800 mV to 27 V. Key electrical parameters include a switching frequency of 410 kHz, quiescent current of 500 uA, and load regulation of 1.5%. It operates within a temperature range of -40°C to +125°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

High efficiency synchronous step-down conversion architecture
Integrated shutdown control functionality
Industrial grade reliability for wide temperature operation

Voltage Regulators - DC DC Switching Regulators Applications

Industrial equipment power distribution
Embedded system voltage regulation
General purpose DC-DC conversion

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix Z indicates reel packaging configuration against official MPS documentation. Confirm that the 4 V to 30 V input range applies strictly to this variant. Ensure compatibility with standard surface mount assembly processes for the QFN-8 footprint. Cross-reference the 410 kHz switching frequency in design simulations.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 410 kHz frequency is required for EMI management. The 3 A current rating suits moderate load applications. Verify that the 30 V maximum input voltage aligns with the source rail. Consider thermal dissipation requirements for the QFN-8 package under full load conditions.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the MPQ4423 series of synchronous buck converters. It shares architectural similarities with automotive variants like the MPQ4423GQ-AEC1-P but lacks AEC-Q100 qualification. The GQ suffix denotes the specific package and pinout configuration used across the family.
