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.

MARKING DIAGRAMS

Enhanced V ™ 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.
