Multiphase controllers provide fast, accurate regulation with the

control features required to power the next generation of processors in

desktop, workstation and server applications. Combined with external

gate drivers and power components, the NCP5306 implements a

compact, highly integrated buck converter. Enhanced V  control

inherently compensates for variations in both line and load. Current

sharing between phases is achieved by Peak Current Sharing.

The NCP5306 includes Power Good with a programmable lower

threshold.

Applications include Embedded Processor Power and low

voltage/high current power supplies.
