PKL 4000 Series
E
The PKL 4000 Series of high efficiency DC/DC
converters are designed to provide high quality on-board
power solutions in distributed power architectures used
in “Inter-networking” equip-ment in Wireless and
Wired Communications and Datacom applications.
The PKL 4000 Series is an extended version of the
industry standard half brick footprint that has been
enhanced to include two additional output pins for
connection reliability and higher output current. The
PKL Series uses the most advanced patented topology
and synchronous rectification technology and achieves
a typical efficiency up to 92%. This product features
fast dynamic response times and low output ripple,
which are important parameters when supplying low-
voltage logics. Ericsson’s PKL 4000 Series addresses
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 over-voltage protection, under-
voltage protection, over-temperature protection, soft-
start, short circuit protection, remote sense, remote
on/off, and industry standard output trim adjustment.
The PKL 4000 Series also offers the flexibility of
using optional heatsinks when needed, enabling
reduced airflow, extended reliability, and higher
ambient temperature operation. These converters are
manufactured in highly automated manufacturing
lines and meet world-class quality levels.
Ericsson Power Modules is an ISO 9001 (since 1991)
and ISO14001 certified Supplier.
