NCP5314  
Two/Three/Four−Phase  
Buck CPU Controller  
The NCP5314 provides full−featured and flexible control for the  
latest 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 1.2 MHz. Combined with external gate  
drivers and power components, the controller implements a compact,

control inherently compensates for variations in

both line and load, and achieves current sharing between phases. This  
control scheme provides the industry’s fastest transient response,  
reducing the need for large banks of output capacitors and higher  
switching frequency.  
The controller meets VR(M)10.x specifications with all the required  
functions and protection features.
