Product Description
NCP6151S/NCP6151SA/NCP6131S/NCP6131SA 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.
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
Applications
• Desktop and notebook processors
