DALLAS – June 12, 2007 – The Distributed-power Open Standards Alliance (DOSA) has announced 2nd generation standard
footprint and pin out design for 12A and 20A non-isolated point-of-load (POL) DC/DC converters. This 2nd generation of POL standards significantly increases the
current density (Amp/in2) from the 1st generation of DOSA standards, meeting industry demand for high-density POL modules. This new standard establishes
the location of pins, recommended pad layout on customer boards, input and output voltage ranges and critical features and parameters required for
interoperability and second sourcing.

20A Footprint and Pin Out
The Distributed-power Open Standards Alliance (DOSA) was formed to ensure future DC-DC product compatibility and standardization within the
increasingly fragmented power converter market. The goal of the alliance is to establish customer interface standards early in the development cycle,
which include form factors, footprints, pin-outs, feature sets and other parameters that will permit alternative sourcing. The alliance will
cover a broad range of power converters including non-isolated (POL), isolated applications, and intermediate bus converters. In addition to DOSA founding members,
Tyco Electronics Power Systems, Inc. and SynQor, Inc., current members include C&D Technologies, Lambda/TDK, Delta, Ericsson, Artesyn/Emerson, Wall Industries,
Acbel and Belpower.
