Powervation has announced its latest digital DC/DC controllers aimed at servers, high-end desktop, and embedded computing systems. The PV3103, PV3104 and PV3202 boast single and dual phase outputs and support both PMBus and Intel's VR12.5 Serial VID (SVID) bus.

The flexible, fully programmable digital controllers claim to offer precision regulation and telemetry to support the latest high-efficiency computing system designs. The PV3202 is a full-featured VR12.5 dual phase digital controller with auto-control, which provides improved transient performance and real-time adaptive loop compensation. The PV3104 is a single phase controller offered in the standard 5 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 4 x 4mm QFN package, which is geared for high density or compact design needs.

VR12/12.5 digital controller

The series features Powervation's auto-control adaptive compensation, which is a mode of Powervation's xTune auto-tuning architecture that promises to deliver faster transient performance and greatly simplifies the design process and time-to-market. The NV memory and RAM architecture allows designers to flexibly configure and store regulator parameters.

The controllers are designed to deliver optimised performance and to interface with a number of MOSFET driver and DrMOS solutions, to power DDR4 memory and other Intel SVID and PMBus loads. In addition, the devices support 0.6-1.52V output and 375kHz - 1MHz programmable frequency.
