Features
Product shown is the PKB 4713 PINB
The PKB 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 PKB 4000 Series has
the same pinout as an industry standard quarter
brick but only occupies approximately half the
footprint. This makes it extremely well suited for
limited board space applications. The PKB Series
uses patented synchronous rectification technology
and achieves an efficiency up to 92.4% at full
load. The series is presently available in non-
baseplated versions and will be offered in
baseplated and surface mount versions in the near
future. Ericsson's PKB 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
PKB 4000 Series also offers the flexibility of using
a baseplate as well as an optional heatsink 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 9001/14001 certified Supplier.
