NCP5393B 2/3/4-Phase Controller

Pin No. Symbol Description 1 VCCA 5 V supply pin for the NCP5393B. The VCC bypassing capacitance must be connected between this pin and GND (preferably returned to the package flag). 2 GND Small *signal power supply return. This pin should be tied directly to the package flag (expo.

NCP5393B 2/3/4-Phase Controller for CPU Applications The NCP5393B is a multiphase synchronous buck regulator controller designed to power the Core and Northbridge of an AMD microprocessor. The controller has a user configurable two, three, or four phase regulator for the Core and an independent single phase regulator to power the microprocessor Northbridge. The NCP5393B incorporates differential voltage sensing, differential phase current sensing, optional load line voltage positioning,.
