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. These breakthrough features
have been achieved by using the most advanced
patented topology, ultilizing integrated magnetics
and synchronous rectification on a low resistivity
multilayer PCB.
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.
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

Stress in excess of Absolute Maximum Ratings may cause permanent
damage. Absolute Maximum Ratings, sometimes referred to as "no
destruction limits," are normally tested with one parameter at a time
exceeding the limits of output data or electrical characteristics. If exposed
to stress above these limits, function and performance may degrade in an
unspecified manner.
