distributed power architecture (power supply) (DPA)

Distributed Power Architecture (DPA) is a concept for generating regulated supply voltages for telecommunication boards.

The Distributed Power Architecture differs from the Intermediate Bus Architecture( IBA) in that there are several PoL converters on each board for generating the supply voltages; directly where the voltage is needed. The central supply voltage of -48 V is converted in several DC/DC converters to the various lower supply voltages for the individual boards, although the efficiency of the direct conversion from 48 V to 3.3 V is reduced. In contrast, the IBA architecture uses central DC/DC converters.
