NCP81241: Single-Phase Controller with SVID Interface for Desktop and Notebook CPU Applications
The NCP81241 Single-Phase buck solution is optimized for Intel VR12.1 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 single phase controller uses DCR current sensing providing the fastest initial response to dynamic load events at reduced system cost.
