Compliant with Intel's VR12.5 and VR12 voltage regulation specifications, the TPS53661, TPS53641 and TPS53631 DC/DC controllers and CSD95372B and CSD95373B NexFET smart power stages are a state-of-the-art, digital multiphase solution to power the latest Intel Xeon processors.

The complete solution features industry-leading efficiency at up to 95-percent in the smallest footprint.

The TPS53661, TPS53641 and TPS53631 DC/DC controllers support 6-, 4- and 3-phase operation respectively, and incorporate TI's advanced D-CAP+ control architecture and a feature-rich PMBus command set.

The CSD95372B and CSD95373B synchronous buck NexFET smart power stage integrate an intelligent driver and power MOSFETs in a compact 5-mm by 6-mm package. Together, the products provide a complete multiphase Vcore system solution with superior transient performance, industry-benchmark telemetry accuracy and outstanding system reliability.

Features:

－ TI's D-CAP+ architecture offers ultra-fast transient response. Its inherent design eliminates beat frequency.

－ Dynamic current sharing and cycle-by-cycle current limit ensure robust multiphase regulator operation.

－ Hybrid analog and digital topology delivers lowest quiescent power consumption, fastest dynamic performance and ultimate flexibility.

－ Industry's smallest 5-mm by 5-mm package.
