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,
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

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.
