ON NCP6151AD52MNR2 Vr12 2-, 3-, 4-phase cpu controller 1-phase gpu controller Datasheet

Product Overview
NCP6151: VR12 2-, 3-, 4-Phase CPU Controller + 1-Phase GPU Controller
For complete documentation, see the data sheet
Product Description
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. It also sheds to single phase during light load operation and can auto frequency scale in light
load while maintaining excellent transient performance.
