Two/Three/FourPhase
Buck CPU Controller
The NCP5314 provides fullfeatured and flexible control for the
latest highperformance CPUs. The IC can be programmed as a two,
three or fourphase buck controller, and the perphase 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 multiphase buck converter.

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.
