MP4248GQV-0012-Z

Overview

The MP4248GQV-0012-Z is a synchronous Buck-Boost switching regulator from Monolithic Power Systems. It operates with an input voltage range of 3.6 V to 36 V and delivers up to 7 A output current. The device supports an adjustable output voltage between 1 V and 36 V, enabling flexible power conversion for varying load requirements. It integrates low-side MOSFETs and features a fixed switching frequency of 580 kHz. The component includes an I2C interface for configuration and high-side current sensing support. It functions within a temperature range of -40°C to +125°C and is housed in a QFN-20 package.

Feature Summary

• Integrated low-side MOSFETs reduce external component count
• I2C interface enables digital control and monitoring
• Supports high-side current sensing for precise regulation

Applications

• Industrial automation systems
• Automotive electronics
• Telecommunications infrastructure

Procurement Notes

Verify the specific suffix Z indicates RoHS compliance and halogen-free status according to manufacturer documentation. Confirm the QFN-20 package dimensions match your PCB footprint design. Ensure the I2C address configuration aligns with your system bus requirements before finalizing procurement.

Selection Notes

Select this component when input voltages vary significantly above or below the desired output level. The Buck-Boost topology handles both step-up and step-down operations efficiently. Consider the 7 A current capability and 580 kHz frequency for balancing size and performance in compact designs requiring wide input ranges.

Part Context

This part belongs to the MP4248 series of synchronous Buck-Boost converters. It is designed for applications requiring robust power management across wide input voltage variations. The integration of digital controls via I2C distinguishes it from purely analog counterparts in the same family.

Replacement Considerations

MP4248GQV-P is a parameter-equivalent alternative within the same product line.
