NCP5395  
Product Preview  
2/3/4-Phase Controller with  
On Board Gate Drivers for  
CPU Applications  
The NCP5395 provides up to a four−phase buck solution which  
combines differential voltage sensing, differential phase current  
sensing, adaptive voltage positioning, and on board gate drivers.  
Dual−edge pulse−width modulation (PWM) combined with inductor  
current sensing reduces system cost by providing the fastest initial  
response to dynamic load events. Dual−edge multiphase modulation  
reduces the total bulk and ceramic output capacitance required to meet  
transient regulation specifications.

The on board gate drivers includes adaptive non overlap and power  
saving operation. A high performance operational error amplifier is  
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
