Overview

NCP5393 2/3/4-Phase Controller for CPU Applications The NCP5393 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 NCP5393 incorporates differential voltage sensing, differential phase current sensing, optional load−line voltage positioning, and programmable VDD and VDDNB offsets to provide accurately regulated power parallel− and serial−VID AMD processors.
