NCP5392QMNR2G

Overview

The NCP5392QMNR2G is a voltage regulator controller IC designed for Intel VR11, VR11.1, and AMD CPU applications. It features four output channels with an input voltage range of 4.75V to 5.25V and an adjustable output voltage range of 0.375V to 1.6V. The device operates within a temperature range of 0°C to 85°C and is housed in a 40-VFQFN exposed pad package (6x6 mm). This component serves as a dedicated controller for multi-phase power delivery systems in high-performance computing environments.

Feature Summary

• Supports Intel VR11, VR11.1, and AMD CPU voltage regulation standards
• Integrates four independent output channels for multi-phase control
• Operates with standard 5V input supply rails

Applications

• Intel VR11 compliant CPU power delivery
• Intel VR11.1 compliant CPU power delivery
• AMD CPU voltage regulation systems

Procurement Notes

Verify component authenticity through authorized onsemi distributors or certified partners. Confirm the specific suffix 'MNR2G' matches the required tape-and-reel packaging format. Check current availability status as the part may be subject to lifecycle changes or obsolescence notices. Ensure compliance with RoHS and REACH regulations for intended deployment regions.

Selection Notes

Select this controller when designing power stages for processors requiring VR11 or VR11.1 specifications. The four-channel architecture suits applications needing simultaneous core and cache voltage generation. Evaluate thermal performance requirements against the 85°C operating limit and the thermal characteristics of the 40-QFN package for adequate heat dissipation.

Part Context

This component belongs to the NCP5392 family of voltage regulator controllers. It is specifically engineered for desktop and server processor power management. The QFN package provides a compact footprint suitable for dense motherboard layouts. It complements external MOSFETs to form complete synchronous buck converter phases.

Replacement Considerations
