NCP5316
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 V2™ 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.
