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.
