PKM 4113 PI
Advanced Specification
126W DC/DC Power Module
48 V Input; 12V Output
The PKM 4000 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 4113 PI module is a new addition to the se-
ries family with 76.2W/in3 at 90% efficiency.
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
4000 series is especially suited for limited board
space and high dynamic load applications
E
Ericsson's PKM 4000 Power Modules address the
converging "New Telecoms" market by specifying
the input voltage range in accordance with ETSI
specifications. Included in the PKM 4000 series are
over-voltage protection, under voltage protection,
over temperature protection, soft-start, and short
circuit protection. The PKM 4000 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.
