MPQ4323CGRHE-33-AEC1-P

Voltage Regulators - DC DC Switching Regulators Overview

The MPQ4323CGRHE-33-AEC1-P is a synchronous step-down converter from Monolithic Power Systems, designed for automotive applications. It features a fixed 3.3 V output voltage and supports up to 3 A continuous output current. The device operates with an input voltage range of 3.3 V to 36 V and withstands 42 V load dump events. It utilizes a QFN-14 package and offers a switchable frequency between 350 kHz and 2.5 MHz. Key electrical parameters include a quiescent current of 1 uA in shutdown mode, operation across a junction temperature range of -40 C to +150 C, and AEC-Q100 qualification.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Integrated high-side and low-side power MOSFETs for efficient synchronous buck conversion
Robust 42 V load dump tolerance suitable for harsh automotive input environments
Ultra-low 1 uA shutdown current enabling extended battery life in standby modes
Configurable switching frequency allows optimization for efficiency or EMI performance

Voltage Regulators - DC DC Switching Regulators Applications

Automotive infotainment system power distribution
Telematics control unit voltage regulation
ADAS sensor module power supply conditioning
Body control module auxiliary power rails

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix indicates the fixed 3.3 V output variant rather than adjustable versions. Confirm AEC-Q100 Grade 1 qualification status matches project requirements. Ensure thermal design accounts for the QFN-14 package dissipation characteristics under maximum load conditions. Cross-reference pinout compatibility if replacing legacy components in existing PCB layouts.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 3.3 V rail is required without external feedback resistors. Consider the QFN-14 package size constraints against available board space. Evaluate the 3 A current capability against peak load demands including transient spikes. Verify that the 36 V maximum input voltage aligns with the system's nominal bus voltage before finalizing the bill of materials.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the MPQ4323 family of automotive-grade synchronous buck converters. The series is characterized by high efficiency and wide input voltage ranges tailored for vehicle electrical systems. The GRHE suffix denotes the specific QFN-14 package configuration and thermal pad design distinct from other variants in the lineup.
