NCP5306
NCP5306 is Three-Phase VRM 9.0 Buck Controller manufactured by onsemi.
features required to power the next generation of processors in desktop, workstation and server applications. bined with external gate drivers and power ponents, the NCP5306 implements a pact, highly integrated buck converter. Enhanced V2™ control inherently pensates 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. Features http://onsemi.
