Primarion has announced a reference design for its PMBus-compliant PX7522-based solution with dual rails, high efficiency, small footprint and a full digital feature set.

The reference design demonstrates 95 percent efficiency at 5V and 94 percent at 3.3V in under 2 inches? for dual-output POL applications.

Today's soaring energy costs have driven overall awareness to improve power efficiency at every level, particularly in the server and IT equipment industries. Currently, these industries only have proprietary and expensive solutions available to address these power-efficiency challenges. Primarion's PX7522-based solution provides customers with access to non-proprietary digital technology. The solution promises the highest efficiency in the industry without increasing overall cost.

"We are proud to provide the industry and our customers with a record-breaking POL solution that addresses three of today's most critical requirements in power deliveryefficiency, space and low cost," said Deepak Savadatti, Primarion's VP of marketing. "The PX7522-based solution is totally optimized, and combines the highest efficiency levels in the industry with the many user-friendly digital power features that Primarion's solutions have become known for."

The PX7522-based solution features Primarion's next-generation PowerCode (PC) 2.0, an easy-to-use GUI in a design environment. Configurations are easily loaded, edited and saved to non-volatile memory over the device's PMBus serial interface.

The PC 2.0 uses an intuitive graphical interface to provide a user-friendly design environment. It is also an analytical tool that takes the complexity out of designers' hands. It automates the design process with its design wizard and walks the user step-by-step through designing a new DC/DC converter, modifying a current design or evaluating actual hardware. The PC 2.0 enables design, analysis and optimization of the solution, without having the designer devote time to software programming.
