Programmable DC-DC controllers for servers and high-end computing

Powervation has 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 5mm x 5mm QFN package and is footprint compatible with the PV3202. Completing the family of SVID controllers is the PV3103, an ultra-small, digital synchronous buck controller in the 4mm x 4mm QFN package - ideal 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 xTuneT auto-tuning architecture, which delivers faster transient performance and greatly simplifies the design process and time-to-market. The unique NV memory and RAM architecture allows designers to flexibly configure and store regulator parameters, says the company. "We are very pleased by the strong adoption of our VR12.5 controllers to date in the high performance computing space," said David New, vice president of product marketing, Powervation: "This new 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." The new controllers are flexibly designed to deliver optimized 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. Samples and production quantities of the RoHS compliant devices are available now, says the company.
