NCP5399FTR2G Description

NCP5399FTR2G  is a one or two?phase buck controller provided by ON Semiconductor. Differential voltage and current sensing, and adaptive voltage positioning are combined to power Intel VR10.x processors. Dual?edge pulse?width modulation (PWM) combined with inductor current sensing is able to provide the fastest initial response to transient load events, thus system cost can be reduced. total bulk and ceramic output capacitance required to satisfy transient load?line regulation can be reduced based on staggered phase modulation.
