The PKM 4000E series of high efficiency DC/DC
converters are designed to provide high quality on-board
power solutions in distributed power architectures used
in Internetworking equipment in wireless and wired
communications applications . The PKM 4000E series
has industry standard quarter brick footprint and pin-out
and is only 8 .5 mm (0 .33 in) high . This makes it extremely
well suited for narrow board pitch applications with board
spacing down to 15 mm (0 .6 in) . The PKM 4000E series
uses patented synchronous rectification technology and
achieves an efficiency up to 90% at full load . Ericsson’s
PKM 4000E series addresses both the industrial and the
emerging telecom market for applications in the multi-
service network by specifying the input voltage range in
accordance with ETSI specifications . Included as standard
features are output over-voltage protection, input under-
voltage protection, over temperature protection, soft-start,
output short circuit protection, remote sense, remote control,
and output voltage adjust function . These converters are
designed to meet high reliability requirements and are
manufactured in highly automated manufacturing lines and
meet world-class quality levels .
Ericsson Power Modules is an ISO 9001/14001 certified
supplier .

Quality Statement
The PKM 4000E DC/DC converters are designed and
manufactured in an industrial environment where quality
systems and methods like ISO 9000, 6σ (sigma), and SPC
are intensively in use to boost the continuous improvements
strategy . Infant mortality or early failures in the products are
screened out and they are subjected to an ATE-based final
test . Conservative design rules, design reviews and product
qualifications, plus the high competence of an engaged work
force, contribute to the high quality of our products .

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 .
