NCP5387 2/3/4 Phase Controller for CPU Applications The NCP5387 is a two , three , or four phase buck controller which combines differential voltage and current sensing, and adaptive voltage positioning to power both AMD and Intel processors. 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 r.
