com NCP5306 Three−Phase VRM 9.
0 Buck Controller 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 V2™ 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.
