NCP5316
Four/Five/Six鈭扨hase
Buck CPU Controller
The NCP5316 provides full鈭抐eatured and flexible control for the
latest high鈭抪erformance CPUs. The IC can be programmed as a four鈭?
five鈭?or six鈭抪hase buck controller, and the per鈭抪hase 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鈭抪hase buck converter.

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.
