MP4245GVE-0001-Z

Overview

The MP4245GVE-0001-Z is a buck-boost converter from Monolithic Power Systems designed for USB Power Delivery applications. It supports up to 60W power conversion with a peak output current of 6A. The device operates within an input voltage range of 4V to 36V and provides an adjustable output voltage from 1V to 23V. It integrates four power switches with low RDS(ON) values and offers selectable switching frequencies of 250kHz, 350kHz, or 420kHz. The component includes an I²C interface and MTP memory for programmable configuration.

Feature Summary

• Integrates an I²C interface and MTP memory for dynamic parameter configuration including mode selection and line drop compensation.
• Features four internal power switches with optimized on-resistance for efficient buck-boost operation across wide voltage ranges.
• Includes comprehensive protection mechanisms such as constant current limiting, output over-voltage protection, and thermal shutdown.
• Supports EN shutdown active discharge and load-shedding alert functions for enhanced system power management.

Applications

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

Procurement Notes

Verify the specific suffix against official MPS documentation to ensure correct MTP pre-configuration. Confirm package availability and lead times through authorized distributors. Check for RoHS compliance status and moisture sensitivity levels before storage. Ensure ESD handling procedures are followed during assembly. Validate pinout compatibility if substituting other variants in the MP4245 series.

Selection Notes

Select this component for designs requiring flexible voltage regulation between 4V and 36V inputs. The integrated I²C interface allows for software-defined adjustments without hardware changes. Consider the QFN-21 package size for space-constrained PCB layouts. Evaluate the need for external synchronization if multiple converters operate in close proximity. Verify that the required output current does not exceed the 6A peak rating under all operating conditions.

Part Context

This part belongs to the MP4245 series of switch-mode regulators from Monolithic Power Systems. The series focuses on high-efficiency power delivery solutions compatible with modern fast-charging standards. Other variants in the family share similar pinouts but differ in factory-programmed MTP settings. The MP4245GVE-0001-Z is specifically tailored for applications needing precise digital control via I²C.
