NCP5387 Description
NCP5387 2/3/4 Phase Controller for CPU Applications The NCP5387 is a two−, three−, or four−phase buck controller which bines differential voltage and current sensing, and adaptive voltage positioning to power both AMD and Intel processors. Dual−edge pulse−width modulation (PWM) bined with inductor current sensing reduces system cost by providing the fastest initial response to transient load events. Dual−edge...
