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 V2control
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.
