NCP5318
Two/Three/Four?Phase
Buck CPU Controller
The NCP5318 provides full ? featured and flexible control
conforming to the Intel ? VRM 10.1 specification for
high ? performance CPUs. The IC can be programmed as a two ? ,
three ? or four ? phase buck controller, and the per ? phase switching
frequency can be as high as 1.0 MHz. Combined with external gate
drivers and power components, the controller implements a compact,
highly integrated multi ? phase buck converter.
Enhanced V 2 ? control inherently compensates for variations in
both line and load, and achieves current sharing between phases. This
