MPQ4263GQVE-0001-AEC1-Z

Overview

The MPQ4263GQVE-0001-AEC1-Z is an automotive-grade Buck-Boost converter from Monolithic Power Systems, designed for high-power applications. It integrates two Low-Side MOSFETs and delivers up to 140W of peak output power. The device supports a 3.6V to 36V input voltage range and provides a programmable output voltage from 1V to 36V. Key electrical parameters include selectable switching frequencies of 280kHz, 420kHz, or 580kHz, and up to 98% peak efficiency. It features an I²C interface with One-Time Programmable memory for configuration.

Feature Summary

• Integrates two Low-Side MOSFETs with an external gate driver for High-Side MOSFETs to support high-power buck-boost conversion.
• Features an I²C interface and One-Time Programmable memory for configurable reference voltage, switching frequency, and operational modes.
• Includes specialized control strategies for smooth transient response between buck, boost, and buck-boost modes across the full input range.
• Provides accurate output current monitoring and limit functions, supporting USB PD 3.1, EPR AVS, and PPS specifications.

Applications

• Automotive DC power supplies
• USB PD Hubs
• USB PD charging ports
• Wireless charging applications

Procurement Notes

Verify the specific suffix AEC1-Z confirms automotive qualification and tape-and-reel packaging. Confirm the selected switching frequency option (280kHz, 420kHz, or 580kHz) matches the design requirements, as this may vary by sub-part number. Ensure compatibility with external High-Side MOSFET selection, as only Low-Side FETs are integrated. Check for required evaluation boards such as EVQ4262-QVE-00A if available for the specific variant.

Selection Notes

Select this component for designs requiring high peak power density and wide input/output voltage ranges in automotive environments. Consider the need for external High-Side MOSFETs and associated gate drive circuitry. Evaluate thermal management requirements for 140W peak power delivery. Verify that the I²C configuration capabilities align with system flexibility needs. Compare against lower-power variants like the MPQ4262 if 100W is sufficient.

Part Context

This part belongs to the MPQ4263 series of Buck-Boost converters from Monolithic Power Systems. It is distinct from the MPQ4262, which offers lower peak power (100W). The series is characterized by its integrated Low-Side MOSFETs and flexible I²C configuration options. It is specifically qualified for automotive applications under AEC-Q100 standards.

Replacement Considerations

MPQ4263GQVE-0001-AEC1-P is a pin-compatible alternative with different packaging (tray vs. reel). For lower power needs, consider the MPQ4262GQVE-0001-AEC1-Z. No direct functional substitutes with integrated High-Side FETs are listed in the provided data.
