MP4245GVE-0000-Z

Overview

The MP4245GVE-0000-Z is a buck-boost converter with four integrated power switches, designed for USB Power Delivery applications. It delivers up to 6A peak output current within specific input voltage ranges and features excellent load and line regulation. The device supports a wide operating input voltage range of 4V to 36V and provides an adjustable output voltage from 1V to 23V. It includes selectable switching frequencies of 250kHz, 350kHz, or 420kHz, alongside spread spectrum capabilities. Protection mechanisms include constant current limiting, output over-voltage protection, and thermal shutdown.

Feature Summary

• Supports flexible configuration via I2C interface and multiple-time programmable memory
• Provides comprehensive fault protection including CC limiting, OVP, and TSD
• Enables precise control through line drop compensation and load-shedding alerts

Applications

• USB Type-C with PD charging only ports
• 12V bus voltage supplies
• Wireless charging systems

Procurement Notes

Verify the component against official Monolithic Power Systems datasheets to confirm pinout compatibility and electrical specifications. Ensure that the selected switching frequency and package variant align with the target design requirements. Cross-reference the part number suffixes to validate any specific manufacturing or testing configurations. Confirm availability status as this series may be subject to lifecycle changes.

Selection Notes

Select this component for designs requiring high efficiency in variable input voltage environments. Consider the I2C interface for dynamic adjustment of output parameters. Evaluate the thermal performance given the QFN-21 package constraints. Verify that the external component selection meets the minimal BOM requirement while satisfying ripple and transient response targets.

Part Context

This part belongs to the MP4245 series of switch-mode regulators. It is positioned as a solution for power delivery applications where input voltages may vary significantly relative to the required output level. The series emphasizes integration to reduce external component count and board space.
