Multiphase Vcore, PMBus devices offer smart power stage

Compliant with Intel’s VR12.5 and VR12 voltage regulation specifications, the TPS53661, TPS53641 and TPS53631 dc/dc controllers and CSD95372B and CSlD95373B NexFET smart power stages are digital multiphase solutions to power the latest Intel Xeon processors. The multiphase core voltage power management system solution suits enterprise servers, storage and high-end desktop applications. The complete solution features industry-leading efficiency up to 95%.

The dc/dc controllers support 6-, 4- and 3-phase operation and incorporate the D-CAP+ control architecture and a PMBus command set. The NexFET smart power stage integrates an intelligent driver and power MOSFETs in a compact 5- by 6-mm package. The D-CAP architecture offers fast transient response and it eliminates beat frequency. The power stages offer best-in-class thermal performance.
