Consortium releases digital point-of-load spec. for high current applications

The ‘teraAMP’ standard adds to previous specifications announced by AMP Group for digital POL and advanced bus dc-dc converters.

Building on the four initial specifications it published in November 2014, the Architects of Modern Power (AMP Group) consortium today announced a further standard aimed at establishing common mechanical and electrical specifications for the development of advanced power conversion technology for distributed power systems. The ‘teraAMP’ standard, designed for non-isolated digital point-of-load (POL) DC-DC converters, will extend the current range from 90 to 120A while supporting both vertical and horizontal mechanical configurations.

The formation of the AMP Group (currently comprisingcomprise CUI, Ericsson Power Modules and Murata) announced in October 2014, saw a need for true multi-sourced but technically advanced and highly efficient power supplies for distributed power architectures, in telecom, datacom and other industries.

Previous attempts to standardise power supplies typically only addressed the mechanical aspects of their design, i.e. the physical dimensions and pin locations. AMP Group aims to extend standardisation to electrical specifications and performance, including the monitoring, control and communications functions made possible by the adoption of digital controllers. This allows AMP to define common configuration files to enable plug-and-play interoperability between products from its member firms.

The ‘teraAMP’ standard adds to the previous ‘microAMP’ and ‘megaAMP’ standards for digital POLs that covered 20 to 25A and 40 to 50A designs respectively. All these allow for both horizontal and vertical configurations. The first products meeting this ‘teraAMP’ standard are due to be introduced in mid-March 2015.

“The teraAMP standard is the next step in high density, high complexity power design support,” aserts Mark Adams (CUI), as AMP Group spokesperson. “As chip architectures continue to reduce and on-board power requirements increase, it is imperative that the power industry keeps pace by providing high current density solutions at the point of load.”

Alongside the digital POL standards, AMP has also defined two standards for advanced bus DC-DC converters: the ‘ABC-ebAMP’ standard relates to advanced bus bricks measuring 58.42 x 22.66 mm and ranging from 264 to 300W, while the
