NCP6151NS52MNR2G

Overview

The NCP6151S52MNR2G is a VR12-compliant multi-phase CPU controller designed for desktop and notebook applications. It supports dual-output configurations with up to four phases for the CPU core and one phase for the GPU. The device integrates a single Serial VID (SVID) interface for communication with the processor. Operating as a buck topology controller, it features an adjustable switching frequency range from 200 kHz to 1 MHz and supports a maximum duty cycle of 100%. The component is housed in a QFN-52 package and operates within a temperature range of -10°C to +125°C.

Feature Summary

• Supports dual-output architectures with configurable phase counts for CPU and GPU power delivery
• Integrates a single Serial VID interface for direct processor communication and configuration
• Features adjustable switching frequency to optimize efficiency across varying load conditions
• Complies with Intel VR12 specifications for modern mobile and desktop processors

Applications

• Desktop computer motherboard CPU power stages
• Notebook and laptop system-on-module power management
• High-performance computing platforms requiring VR12 compliance

Procurement Notes

Verify the exact suffix against official onsemi documentation, as variations may exist between S52MNR2G and similar designations. Confirm current production status, as this model has been identified as obsolete or end-of-life in some distributor records. Ensure compatibility with existing PCB footprints for the QFN-52 package before procurement.

Selection Notes

Select this controller for designs requiring integrated multi-phase control without external microcontrollers. It is suitable for systems needing precise voltage regulation via SVID. Consider thermal performance and layout requirements for the QFN-52 package. Verify that the target processor supports the VR12 standard and single-line SVID communication protocol.
