Overview

NCP6151/NCP6151A Dual Output 4 Phase +1/0 Phase Controller with single SVID Interface for Desktop and Notebook CPU Applications http://onsemi.com The NCP6151/NCP6151A dual output four plus one phase buck solution is optimized for Intel VR12 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 applications.

The control system is based on Dual-Edge pulse-width modulation (PWM) combined with DCR current sensing providing the fastest initial response to dynamic load events and reduced system cost.

Key Features

  • Meets Intel VR12/IMVP7 Specifications.
  • Current Mode Dual Edge Modulation for Fastest Initial Response to Transient Loading.
  • Dual High Performance Operational Error Amplifier.
  • One Digital Soft Start Ramp for Both Rails.
  • Dynamic Reference Injection® (Patent #US07057381).
  • Accurate Total Summing Current Amplifier(Patent #US006683441).
  • DAC with Droop Feed-forward Injection(Patent Pending).
  • Dual High Impedance Differential Voltag.
