1/2 Phase Controller for  
CPU and Chipset  
Applications  
The NCP5386 is a one− or two−phase buck controller which  
combines differential voltage and current sensing, and adaptive  
voltage positioning to power both AMD and Intel processors and  
chipsets. Dual−edge pulse−width modulation (PWM) combined with  
inductor current sensing reduces system cost by providing the fastest  
initial response to transient load events. Dual−edge multi−phase  
modulation reduces total bulk and ceramic output capacitance  
required to satisfy transient load−line regulation.  
A high performance operational error amplifier is provided, which  
allows easy compensation of the system. The proprietary method of  
Dynamic Reference Injection (Patented) makes the error amplifier  
compensation virtually independent of the system response to VID  
changes, eliminating tradeoffs between overshoot and dynamic VID  
performance.
