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.
These breakthrough features have been achieved by
using the most advanced patented topology, ultiliz-
ing integrated magnetics and synchronous rectifica-
tion 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 such as
demanding microprocessors.
E
Ericsson's PKM 4000A Power Modules address the
converging "New Telecoms" market by specifying
the input voltage range in accordance with ETSI
specifications. The PKM 4000A series also offers
over-voltage protection, under voltage protection,
over temperature protection, soft-start, and is short
circuit proof.
These modules are manufactured using highly auto-
mated manufacturing lines with a world-class quali-
ty commitment and a five-year warranty. Ericsson
Inc., Microelectronics has been an ISO 9001 certi-
fied supplier since 1991.
