Datasheet Summary
Dual Output 3 Phase +1/0 Phase Controller with Single SVID Interface for Desktop and Notebook CPU Applications http://onsemi.
The NCP6121 dual output three plus one phase buck solution is optimized for Intel VR12 patible CPUs. The controller bines true differential voltage sensing, differential inductor DCR current sensing, input voltage feed- forward, and adaptive voltage positioning to provide accurately regulated power for Desktop applications. The control system is based on Dual- Edge pulse- width modulation (PWM) bined with DCR current sensing providing the fastest initial response to dynamic load events and reduced system cost. It also sheds to single phase during...
