NCP5425  
Dual Synchronous  
Buck Controller  
The NCP5425 is a highly flexible dual buck controller with internal  
gate drivers that can be used with two input power supplies and one or  
two outputs in multiple configurations. The part contains all the  
circuitry required for two independent synchronous dual NFET buck  
regulators utilizing a feed forward voltage mode control method. The  
NCP5425 can run from a single supply ranging from 4.6 to 12 volts  
and support a single two phase or dual single phase outputs. When  
used as a dual output controller, the second output tracks voltage  
transients from the first. Power blanking for low noise applications is  
supported as well as independent cycle−by−cycle current limiting. The  
part is available in a 20 pin TSSOP package allowing the designer to  
minimize PCB area.
