NCP6151/NCP6151A  
Dual Output 4 Phase +1/0 Phase  
Controller with single SVID Interface  
for Desktop and Notebook CPU  
Applications  
hm  
The NCP6151/NCP6151A dual output four plus one  
phase buck solution is optimized for Intel VR12  
compatible CPUs. The controller combines true  
differential voltage sensing, differential inductor DCR  
current sensing, input voltage feed-forward, and  
adaptive voltage positioning to provide accurately  
regulated power for both Desktop and Notebook  
applications. The control system is based on Dual-Edge  
pulse-width modulation (PWM) combined with DCR  
current sensing providing the fastest initial response to  
dynamic load events and reduced system cost. It also  
sheds to single phase during light load operation and  
can auto frequency scale in light load while maintaining  
excellent transient performance.  
Dual high performance operational error amplifiers are  
provided to simplify compensation of the system.  
Patented Dynamic Reference Injection further simplifies  
loop compensation by eliminating the need to  
compromise between closed-loop transient response  
and Dynamic VID performance. Patented Total Current  
Summing provides highly accurate current monitoring for  
droop and digital current monitoring.
