Providing precision regulation and telemetry to support the latest high efficiency computing system designs, a series of flexible programmable digital DC/DC controllers for servers, high-end desktop, and embedded computing systems has been released by Powervation. 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 PV3202 is Powervation’s latest full-featured VR12.5 dual phase digital controller with Auto-Control, which provides transient performance and real-time adaptive loop compensation.  The PV3104 is a single phase controller offered in the standard 5x5mm QFN package and is footprint compatible with the PV3202. Completing the family of SVID controllers is Powervation’s PV3103, a tiny digital synchronous buck controller in the 4x4mm QFN package, suitable for high density or compact design needs.

The series features Powervation’s unique Auto-Control adaptive compensation, which is a mode of Powervation’s leading xTune auto-tuning architecture, delivering faster transient performance and a simplified design process. The NV memory and RAM architecture allows designers to flexibly configure and store regulator parameters.

The controllers are flexibly designed to deliver optimised performance and to interface with most leading MOSFET driver and DrMOS solutions, to power DDR4 memory and other Intel SVID and PMBus loads for server, storage, high performance computing and communications systems. The RoHS-compliant devices are available now for sample and production orders.

“We are very pleased by the strong adoption of our VR12.5 controllers to date in the high performance computing space,” commented David New, Vice President of Product Marketing, Powervation.  “This series of digital SVID controllers provides higher performance and new features, and extends our portfolio of auto-tuning digital controller solutions for low- and mid-power SVID and PMBus applications.”
