MP4255GVE-0002-P

Overview

The MP4255GVE-0002-P is a dual-channel synchronous buck converter from Monolithic Power Systems, designed for power delivery applications. It operates with an input voltage range of 4 V to 36 V and provides two independent outputs adjustable from 1 V to 36 V. Each channel delivers up to 3 A of output current. The device features an I2C interface for configuration and control, supporting dynamic voltage scaling. It includes a shutdown function and operates within a temperature range of -40°C to +125°C.

Feature Summary

Dual-channel synchronous buck topology for independent power rail generation
I2C interface enables digital control and monitoring capabilities
Wide input voltage range supports various bus architectures
Integrated shutdown functionality for system power management

Applications

Power delivery systems requiring multiple regulated rails
Industrial equipment with diverse voltage requirements
Communication infrastructure power modules
Embedded systems needing programmable voltage outputs

Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm pinout compatibility and electrical characteristics. Ensure that the procurement source provides valid traceability and authenticity certificates. Confirm that the component meets all relevant environmental compliance standards required for your specific application environment before finalizing acquisition.

Selection Notes

Select this component when dual isolated or non-isolated buck conversions are needed from a single wide-range input source. The I2C capability makes it suitable for systems requiring dynamic voltage adjustment. Consider thermal management requirements given the 3 A per channel output capability in the QFN-21 package. Evaluate if the fixed switching frequency meets EMI constraints for the target design.

Part Context

This part belongs to the MP4255 series of dual buck converters from Monolithic Power Systems. It is part of a family of PMICs designed for complex power delivery networks. The GVE package indicates a specific QFN footprint optimized for surface mount assembly. The series focuses on providing flexible power solutions for modern electronic systems with strict size and efficiency demands.
