DIFFERENTIAL CURRENT SENSING FOR VRD10.X DESCRIPTION The NX2411 is a three-phase PWM controller with integrated FET driver designed to provide a low cost high current multiphase converter that meets the VRD10.0 specification. Multiphase synchronous buck converter offers ripple cancelation for both input and output.The NX2411 uses differential remote sensing using either current sense resistor or inductor DCR sensing to achieve accurate current matching between the three channels. Differential sensing eliminates the error caused by PCB board trace resistance that is otherwise present when using a single ended voltage sensin
