AMP power group adds 60A PoL DC/DC to 2nd-sourced range

September 21, 2016 // By Graham Prophet
Architects of Modern Power – AMP – is a co-operative grouping of CUI, Ericsson Power Modules and Murata, who work together to offer de-facto “standard” formats of commonly required power conversion products, with the aim that a customer should always be able to find a true fit/form/function second-source unit for a range of units.

The alliance has now added a specification for a non-isolated digital point-of-load standard for 60 A output DC/DC converter; joining previously-released non-isolated DC/DC specifications, this one is called ‘gigaAMP’.

The standard sets out a mechanical and electrical specification; the AMP group, as part of its operation, promises tht at least two of the three companies will produce independently-manufactured product conforming to the specification. The manufacturing path is second-sourced; the range does involve exchange of design information between the participating companies, in order to ensure fully-compatible operation in all aspects of a power module offering advanced power conversion technology for distributed power systems.

The ‘gigaAMP’ standard, introduced to provide a higher current option in a land-grid array (LGA) footprint, builds on the previously-released ‘picoAMP’ standard, published in September 2015, which defined standards for a lower range of non-isolated platforms ranging from 6A to 18A. The 60A ‘gigaAMP’ standard defines a compact footprint of 25.1 x 14.1 mm in an LGA format. As with other specification offered by the group, the converters will have fully matching features sets, and compatible configuration files and formats. This will allow a second-source prouct to be ‘dropped in’ to a production run, including where configuration is by digital download at final test stage, without disruption.

The ‘gigaAMP’ standard also adds to the previously released ‘teraAMP’ standard for non-isolated digital point-of-load (POL) dc-dc converters, released in February 2015, and the ‘microAMP’ and ‘megaAMP’ standards from November 2014. The first products to meet with this new ‘gigaAMP’ standard will be announced by AMP Group members later in 2016. (The illustration is of one of Ericsson’s modules, BMR463, conforming to “microAMP”).
