MP4248GQV-0012-P

Overview

The MP4248GQV-0012-P is a synchronous Buck-Boost switching regulator manufactured by 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 from 1 V to 36 V and integrates low-side MOSFETs. Key electrical parameters include a typical quiescent current of 775 uA and a fixed switching frequency of 580 kHz. It functions within a temperature range of -40°C to +125°C and utilizes a QFN-20 package for surface mount installation.

Feature Summary

• Supports Buck-Boost topology for wide input and output voltage flexibility
• Integrates low-side MOSFETs to reduce external component count
• Includes I2C interface for digital control and monitoring
• Supports high-side current sensing for precise regulation

Applications

• Industrial automation systems requiring flexible power rails
• Battery-powered equipment with varying source voltages
• Automotive electronics operating under wide voltage fluctuations
• Portable devices needing efficient step-up and step-down conversion

Procurement Notes

Verify the specific suffix 'P' against official MPS documentation to confirm packaging details, as datasheets may primarily reference 'Z' variants. Ensure compatibility with required I2C addressing and current sense configurations during procurement planning. Cross-reference the exact part number with manufacturer release notes to confirm availability status and lifecycle stage before finalizing orders.

Selection Notes

Select this component when designing systems requiring both buck and boost capabilities from a single IC. The integrated low-side MOSFETs simplify thermal management compared to discrete solutions. Consider the 580 kHz switching frequency for balancing efficiency and passive component size. Verify that the 7 A output capability meets peak load requirements while maintaining operation within the specified temperature range.

Part Context

This part belongs to the MP4248 series of synchronous Buck-Boost regulators from Monolithic Power Systems. The series is designed for applications demanding high efficiency and wide input voltage ranges. The MP4248GQV variant specifically features a QFN-20 package and digital interface support, distinguishing it from basic analog-only counterparts in the broader PMIC portfolio.

Replacement Considerations
