NCP81568MNTXG

Overview

The NCP81568MNTXG is a single-phase synchronous buck switching voltage regulator designed for high-performance computing applications. It integrates power MOSFETs and supports the Intel SVID interface with IMVP9.2 protocol compliance. The device delivers up to 40A ICCMAX output current and features ultra-low offset IOUT monitoring with DCR detection. It includes differential remote voltage sensing, soft transient control, and programmable frequency operation within a compact QFN48 package.

Feature Summary

• Integrates power MOSFETs and SVID interface controller for simplified design
• Provides ultra-low offset current monitoring with DCR sensing capability
• Features soft transient control to reduce inrush current and audible noise
• Supports dynamic VID feedforward and external programmable droop gain

Applications

• Desktop computer motherboards
• Laptop systems
• Ultrabook platforms

Procurement Notes

Verify the specific suffix MNTXG against the manufacturer datasheet to confirm packaging type and tape/reel specifications. Ensure compatibility with Intel IMVP9.2 signaling requirements for the target platform. Confirm that the QFN48 footprint matches the PCB layout guidelines provided in the official documentation before finalizing procurement orders.

Selection Notes

Select this component when a single-chip solution integrating drivers and power stages is required for CPU core voltage regulation. It is suitable for designs needing precise current monitoring via DCR sensing and low acoustic noise through soft transient control. Consider the thermal performance of the QFN48 package relative to the expected 40A load conditions.

Part Context

This part belongs to the onsemi NCP8156x series of single-phase VR controllers. It is engineered specifically for next-generation mobile and desktop processors requiring fast transient response and high efficiency. The integration of the SVID interface allows direct communication with the processor for dynamic voltage scaling.

Replacement Considerations

Check for updated revisions within the NCP81568 family or compatible IMVP9.2 compliant regulators from onsemi. Verify pin-to-pin compatibility if substituting with other single-phase VRMs. Ensure any alternative maintains support for the required SVID protocol version and current delivery capabilities.
