The ‘HPABC‑qbAMP’ standard establishes common mechanical and electrical specifications for high power advanced bus DC-DC converters in distributed power systems to keep designers of high-performance datacom and telecom equipment one step ahead as cloud computing and IoT drive hgher power density requirements. 

The standard builds upon the previous “ABC‑ebAMP’ and ‘ABC‑qbAMP’ specifications that defined pinouts and footprints for eighth brick and quarter brick advanced bus modules ranging from 264 to 300 W and 420 to 468 W, respectively. Measuring 58.42 x 36.83 mm, the ‘HPABC‑qbAMP’ standard occupies the same board space as a standard quarter brick converter. The new specification defines the mechanical and electrical specifications for analogue and digital versions, as well as compatible software configuration files for the digital version. The first products using the ‘HPABC‑qbAMP’ standard will be announced by AMP Group members – CUI, Ericsson Power Modules and Murata – early next year.

“This new standard continues our commitment to provide leading-edge power technology in support of our belief that advanced power is becoming a must have across various industries,” said Martin Hägerdal, President of Ericsson Power Modules, while Murata Power Solutions’ President & CEO, Steve Pimpis, added, “Ultimately, the introduction of the ‘HPABC-qbAMP’ standard is the AMP Group’s next step in supporting designers as power and performance demands continue their steady climb upwards.”

The AMP Group is an alliance formed in 2014 between the three companies to define a true multi-sourced, high performance power ecosystem for distributed power architectures. AMP Group members have set out to agree upon common mechanical and electrical specifications for their products, including standardization of monitoring, control and communications functions, as well as common configuration files for plug-and-play interoperability between modules from each firm.
