NCP5380MNR2G

Overview

The NCP5380MNR2G is a switching controller designed for Intel VR11 voltage regulator applications. It features a single output channel and operates within an input voltage range of 4.5V to 5.5V. The device supports a maximum switching frequency of 3000 kHz and utilizes pulse width modulation control technology. Packaged in a 32-QFN (5x5 mm) surface-mount format, it functions as a specialized power management IC suitable for high-performance processor power delivery systems.

Feature Summary

Designed specifically for Intel VR11 voltage regulator compliance
Utilizes pulse width modulation for precise voltage regulation
Supports high-frequency operation up to 3000 kHz
Integrated into a compact 32-pin QFN package

Applications

Intel VR11 compliant CPU voltage regulation
High-density server power supply designs
Processor core voltage step-down conversion

Procurement Notes

This component has reached end-of-life status with official discontinuance notifications issued by the manufacturer. Availability is restricted to remaining stock held by distributors or third-party suppliers such as Rochester Electronics. Verification of authenticity and lot traceability is critical when sourcing from non-direct channels due to the discontinued production status.

Selection Notes

Engineers should evaluate this part primarily for legacy system maintenance or specific VR11 compatibility requirements. Given its discontinued status, alternative solutions within the NCP5392 or NCP5395 series may offer better long-term supply chain stability while maintaining similar architectural approaches for Intel processor power management.

Part Context

The NCP5380 belongs to onsemi's portfolio of specialized power management integrated circuits targeting high-performance computing platforms. As a dedicated voltage regulator controller, it addresses the stringent transient response and efficiency demands of modern microprocessors. This specific model represents an earlier generation solution compared to newer multi-phase controllers available in the current product lineup.
