MP4248GQV-0000-Z

Overview

The MP4248GQV-0000-Z is a synchronous Buck-Boost switching regulator from Monolithic Power Systems. It supports an input voltage range of 3.6 V to 36 V and delivers up to 7 A output current. The device provides an adjustable output voltage from 1 V to 36 V with a single output channel. Operating at a fixed switch frequency of 580 kHz, it features integrated low-side MOSFETs and supports high-side current sensing. The component operates within a temperature range of -40 °C to +125 °C and utilizes a QFN-20 package.

Feature Summary

• Synchronous Buck-Boost topology enables seamless operation in step-down, step-up, and pass-through modes without external pre-regulation stages.
• Integrated low-side MOSFETs and support for high-side current sensing simplify circuit design and enhance protection capabilities.
• I2C interface allows for digital control and monitoring of the power supply parameters.

Applications

• Portable DC power supplies requiring wide input voltage adaptability
• Embedded power systems for laboratory debugging and field maintenance
• Battery-powered equipment utilizing lithium-ion or lead-acid sources
• Industrial power adapters supporting variable load conditions

Procurement Notes

Verify the specific suffix Z against official MPS documentation to confirm RoHS compliance and tape-and-reel packaging specifications. Confirm that the QFN-20 package matches the target PCB footprint and thermal requirements. Ensure the I2C address configuration aligns with system bus constraints before finalizing procurement orders.

Selection Notes

Select this component when applications require a single-stage solution for both buck and boost operations across a wide voltage range. The integrated MOSFETs reduce external component count compared to discrete solutions. Consider the 580 kHz switching frequency for balancing efficiency and passive component size. Verify thermal dissipation capabilities for the QFN-20 package under maximum load conditions.
