NCP81245 Three-Rail Output Controller with Single Intel Proprietary Interface for Desktop and Notebook CPU Applications www.
onsemi.
com The NCP81245 (3+3+1 phase) three−output buck solution is optimized for Intel’s IMVP8 CPUs.
The two multi−phase rail control systems are based on Dual−Edge pulse−width modulation (PWM) combined with DCR current sensing providing an ultra fast initial response to dynamic load events and reduced system cost.
The single−phase rail makes use of ON Semiconductor’s patented high performance RPM operation.
RPM control maximizes transient response while allowing for smooth transitions between discontinuous−frequency−scaling operation and continuous−mode full−power ...
