Four/Five/Six−Phase

Buck CPU Controller

The NCP5316 provides full−featured and flexible control for the

latest high−performance CPUs. The IC can be programmed as a four−,

five− or six−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

control inherently compensates for variations in

both line and load, and achieves current sharing between phases. This

control scheme provides fast 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.
