NX2411 - NEXSEM

NX2411 THREE-PHASE PWM CONTROLLER

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 s.
