The PKM 4000A series of DC/DC power modules

represents another Ericsson "industry first" achieve-

ment in the continued development of our "third

generation" of high density, high efficiency DC/DC

power modules in an industry standard quarter

brick package with unparalleled performance. The

PKM 4318A PIOB module is a new addition to the

PKM 4000A series family specifically for low volt-

age silicon devices in a one step conversion at 89%

typical efficiency.

have been achieved by using the most advanced

patented topology, ultilizing integrated magnetics

and synchronous rectification on a low resistivity

multilayer PCB.

The product features fast dynamic response times

and low output ripple, which are important param-

eters when supplying low voltage logics. The PKM

4000A series is especially suited for limited board

space and high dynamic load applications.

Ericsson's PKM 4000A Power Modules address the

converging "New Telecoms" market by specifying

the input voltage range in accordance with ETSI

specifications. Included in the PKM 4000A series

are over-voltage protection, under voltage protec-

tion, over temperature protection, soft-start, short

circuit protection, and industry standard output

trim adjustment. The PKM 4000A Series also offers

the flexibility of using an optional heatsink when

needed, enabling reduced airflow, extended reliabili-

ty, and higher ambient temperature operation.

These modules are manufactured using highly auto-

mated manufacturing lines with a world-class quali-

ty commitment which is reflected in our standard

five-year warranty. Ericsson Inc., Microelectronics

has been an ISO 9001 certified supplier since 1991.
