MPQ4262GQVE-0002-AEC1-Z

Overview

The MPQ4262GQVE-0002-AEC1-Z is an automotive-grade buck-boost switching voltage regulator from Monolithic Power Systems. It integrates two low-side power MOSFETs and supports an I2C interface for configuration. The device operates with an input voltage range of 3.6 V to 36 V and provides a regulated output voltage between 1 V and 36 V. It delivers up to 100 W of peak output power. Key electrical parameters include a maximum operating junction temperature of +150°C, a minimum operating temperature of -40°C, and a typical quiescent current of 775 µA. The switching frequency is fixed at 580 kHz, and the unit features a QFN-20 package with wettable flanks.

Feature Summary

• Integrates two low-side power MOSFETs within a single buck-boost converter topology
• Supports digital control and monitoring via an I2C communication interface
• Qualified for automotive applications under AEC-Q100 standards
• Features high thermal performance with a maximum junction temperature rating of 150°C

Applications

• Automotive infotainment systems requiring wide input voltage ranges
• Electronic Control Units (ECUs) in automotive environments
• Power distribution networks in vehicles with fluctuating battery voltages
• High-power automotive lighting systems

Procurement Notes

Verify the specific ordering suffix to ensure compatibility with required packaging options such as cut tape or reel quantities. Confirm that the wettable flank package variant meets your automated assembly requirements. Ensure the design accounts for the AEC-Q100 qualification level if deploying in certified automotive systems. Cross-reference the datasheet for thermal dissipation needs given the 100W peak capability and QFN-20 footprint.

Selection Notes

Select this component when a wide input voltage range spanning both buck and boost modes is necessary for automotive loads. The integrated low-side MOSFETs reduce external component count compared to discrete solutions. The I2C interface allows for dynamic adjustment of operating parameters, which is beneficial for complex power management strategies. Consider the 580 kHz switching frequency for balancing efficiency and passive component size.
