MP4255GVE-0000-Z

Overview

The MP4255GVE-0000-Z is a dual 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 supports up to 3 A of output current. The device features a fixed switching frequency of 2.1 MHz and includes an I2C interface for configuration. It functions within a temperature range of -40°C to +125°C and is housed in a QFN-21 package.

Feature Summary

• Dual-channel architecture providing independent control over two separate output rails
• I2C interface enables digital programming and monitoring of converter parameters
• Wide input voltage capability accommodates various bus voltage standards
• Integrated shutdown functionality allows for precise power management control

Applications

• Power delivery systems requiring multiple regulated voltage rails
• Industrial equipment needing flexible DC-DC conversion
• Embedded systems utilizing I2C-configurable power sources

Procurement Notes

Verify the specific suffix Z against official MPS documentation to confirm packaging and tape-and-reel specifications. Ensure the QFN-21 footprint matches your PCB layout requirements. Confirm RoHS compliance status through the manufacturer's environmental declaration before finalizing procurement orders.

Selection Notes

Select this component when dual isolated or non-isolated buck outputs are required from a single wide-range input source. The I2C interface is suitable for systems needing dynamic voltage adjustment. Verify that the 3 A per channel rating meets peak load demands without exceeding thermal limits in the QFN-21 enclosure.

Part Context

This part belongs to the MP4255 series of dual synchronous buck converters. It is distinct from single-output variants like the MP4245 or LED drivers such as the MP4425. The GVE suffix indicates the specific QFN-21 package variant within the broader MP4255 family.

Replacement Considerations
