Digital Controller Family with VR12/12.5 Compliant Interface


Powervation Ltd. announced its latest series of digital DC/DC controllers for servers, high-end desktop, and embedded computing systems. The PV3103, PV3104,

and PV3202 devices feature single and dual phase outputs and support both PMBus and Intel’s VR12.5 Serial VID (SVID) bus. The highly flexible, fully programmable digital controllers provide precision regulation and telemetry to support the latest high efficiency computing system designs. The PV3202 is Powervation’s latest full-featured VR12.5 dual phase digital controller with Auto-Control®, which provides superior transient performance and real-time adaptive loop compensation. The PV3104 is a single phase controller offered in the standard 5 mm × 5 mm QFN package and is footprint compatible with the PV3202. Completing the family of SVID controllers is Powervation’s PV3103, an ultra-small, digital synchronous buck controller in the 4 mm x 4 mm QFN package – PV3103 is ideally suited to high density or compact design needs.
