Digital controllers provide auto-tuning for motherboards

The devices provide higher switching frequency, a configurable alert functionality and phase loss fault detection. Additionally, the controllers feature Powervation’s Auto-Control, the auto-tuning mode of Powervation’s xTune adaptive compensation architecture, which simplifies the design process and improves transient performance.

Designed to deliver optimised performance while interfacing with most leading MOSFET driver and DrMOS solutions, the PV3203 and PV3205 are highly flexible and configurable, and have been optimised to power DDR memory, PCH and other POL rails in computing and communications applications. The RoHS compliant devices are available now for sample and production orders. The PowerSMART design tool is offered at no charge, and is available for download from the Powervation website.

“Working closely with leaders in the gaming motherboard space, we developed these products to provide superior transient and jitter performance, while adding features and more configurability to address the needs of this application,” commented David New, Vice President, Product Marketing, Powervation. “With the help of our PowerSMART design tool, users are able to rapidly configure the controllers and optimise their design, delivering a key need for this market sector, time-to-market.”
