NCP4206MNR2G

Overview

The NCP4206MNR2G is a digital programmable multi-phase synchronous buck converter manufactured by onsemi. It serves as an Intel VR11.1 voltage regulator IC featuring six outputs housed in a 48-QFN (7x7) package. The device supports surface mount installation and operates within a temperature range of 0°C to +85°C. Designed for high-efficiency power management, it integrates control logic with switching regulation capabilities suitable for complex processor power delivery systems.

Feature Summary

• Integrates multi-phase synchronous buck conversion with digital programmability
• Supports Intel VR11.1 voltage regulator specifications
• Features six independent output channels for distributed power delivery
• Includes I2C interface for configuration and monitoring

Applications

• Intel VR11.1 compliant CPU voltage regulation
• Multi-core processor power supply units
• High-performance server motherboard power stages
• Digital power management systems requiring phase interleaving

Procurement Notes

Verify component authenticity through authorized distribution channels due to potential counterfeit risks. Confirm RoHS compliance status via current datasheet revisions. Check for end-of-life notifications or product change notices that may affect long-term availability. Ensure storage conditions meet moisture sensitivity level requirements prior to assembly.

Selection Notes

Evaluate thermal performance requirements against the 48-QFN package dissipation capabilities. Verify input voltage ranges match system power rails. Assess PMBus or I2C communication compatibility with existing controller architectures. Consider phase count requirements relative to load transient response needs.

Part Context

Part of the NCP4200 series designed for advanced processor power applications. Shares architectural similarities with NCP4200 but offers increased channel density. Targets high-density computing environments requiring precise voltage tracking and fast transient response.

Replacement Considerations

NCP4200MNR2G offers four outputs instead of six; verify phase count sufficiency. NCP5392PMNR2G provides similar VR11 functionality but differs in output configuration. Cross-reference pinouts and control interfaces before substitution.
