NCP5392PMNR2G

Overview

The NCP5392PMNR2G is a VR11/VR11.1 compatible voltage regulator controller IC designed for Intel and AMD CPU applications. It features four independent output channels with an input voltage range of 4.75V to 5.25V and adjustable output voltages from 0.375V to 1.6V. The device operates within a temperature range of 0°C to 85°C and is housed in a 40-pin QFN (6x6mm) package with an exposed pad. This component serves as a critical power management solution for high-performance processors requiring precise multi-phase control.

Feature Summary

• Supports Intel VR11 and VR11.1 specifications alongside AMD CPU requirements
• Integrates four independent output channels for multi-phase regulation
• Operates on standard 5V input supply rails

Applications

• Intel Core processor voltage regulation modules
• AMD CPU power delivery systems
• Multi-phase VR11 compliant motherboard designs

Procurement Notes

This component has reached End-of-Life (EOL) status as of July 22, 2016. Original manufacturer distribution is discontinued. Availability is limited to secondary market distributors or surplus stock holders. Verify part authenticity and storage conditions carefully when sourcing from non-original suppliers due to the age of the product lifecycle.

Selection Notes

Select this controller only if designing for legacy VR11/VR11.1 architectures or replacing existing units in field repairs. Ensure the system requires exactly four phases and operates within the specified 0-85°C ambient range. New designs should consider modern successors unless strict backward compatibility with older CPU power standards is mandatory.

Part Context

Part of the NCP5392 family, this specific suffix indicates tape-and-reel packaging. It belongs to onsemi's specialized PMIC line for computing platforms. The device integrates gate drivers and control logic optimized for synchronous buck converters used in central processing unit power stages.

Replacement Considerations

Direct substitutes are not officially listed by the manufacturer due to EOL status. Evaluate newer VR12/VR13 controllers for new designs, though pinouts and control interfaces may differ significantly. Secondary market sources may offer equivalent functionality but require rigorous validation.
