NCP6153 Dual Output 3/4 Phase +1/0 Phase Controller with Single SVID Interface for Desktop and Notebook CPU Applications http://onsemi.
com The NCP6153 dual output four plus one phase buck solution is optimized for Intel VR12 compatible CPUs.
The controller combines MARKING DIAGRAM 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 1 52 ...
