MP4255GVE-0001-P

Overview

The MP4255GVE-0001-P is a dual synchronous buck converter from Monolithic Power Systems, designed for power delivery applications. It features an input voltage range of 4 V to 36 V and provides two independent outputs adjustable from 1 V to 36 V. Each channel supports up to 3 A of output current with a switching frequency of 2.1 MHz. The device includes I2C interface control, operates within a temperature range of -40°C to +125°C, and utilizes a QFN-21 package.

Feature Summary

• Dual-channel synchronous buck topology for independent power rail generation
• I2C digital interface for programmable configuration and monitoring
• Wide input voltage compatibility supporting standard bus architectures

Applications

• Power Delivery (PD) systems
• USB Type-C port controllers
• Multi-rail server and storage backplanes

Procurement Notes

Verify the specific suffix 'P' against official MPS documentation to confirm packaging details, as distributor listings may vary in description accuracy. Ensure the component meets RoHS compliance requirements for your target assembly process. Cross-reference the full part number with the manufacturer's latest datasheet to validate pinout and thermal characteristics before finalizing procurement specifications.

Selection Notes

Select this component when designing systems requiring two isolated or non-isolated low-voltage rails from a higher voltage bus. The integrated I2C interface allows for dynamic voltage adjustment and fault monitoring, reducing external component count. Consider the 2.1 MHz switching frequency for balancing efficiency and passive component size in space-constrained layouts.

Part Context

This part belongs to the MP4255 series of dual buck converters optimized for modern power delivery standards. It complements other MPS PMICs by providing high-current dual outputs in a compact footprint. The series is engineered to meet the stringent transient response and efficiency requirements of USB PD and data center infrastructure applications.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Verify compatibility with existing designs by comparing electrical parameters and pinouts directly with the manufacturer's documentation.
