Datasheet
The PKM 2000E series of high efficiency DC/DC convert-
ers are designed to provide high quality on-board power
solutions in distributed power architectures used in
Internetworking equipment in wireless and wired com-
munications applications . The PKM 2000E 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 2000E series
uses patented synchronous rectification technology and
achieves an efficiency up to 90% at full load . Ericsson’s
PKM 2000E 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 con-
trol, 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.
