Overview

NCP81105, NCP81105H DrMOS Supporting, 1/2/3 Phase Power Controller with SVID Interface for Desktop and Notebook VR12.5 & VR12.6 CPU Applications The NCP81105 is a DrMOS supporting controller optimized for Intel® VR12.5 & VR12.6 compatible CPUs.

The controller combines true differential voltage sensing, differential inductor DCR current sensing, input voltage feed−forward, and adaptive voltage positioning to provide accurately regulated power for both Desktop and Notebook CPU applications.

The control system is based on Dual−Edge pulse−width modulation (PWM), to provide the fastest initial response to dynamic load events plus reduced system cost.

Key Features

  • Meets Intel’s VR12.5 Specifications.
  • Implements VR12.6 PS4 State and SVID Reporting.
  • Mixed Voltage/Current Mode, Dual Edge Modulation for Fastest Initial Response to Transient Loading.
  • High Impedance Differential Voltage Amplifier.
  • High Performance Operational Error Amplifier.
  • High Impedance Total Current Sense Amplifier.
  • True Differential Current Sense Amplifiers for Balancing Current in Each Phase.
  • Digital Soft Start Ramp.
