The PKJ series represents a "third generation" of
High Density DC/DC Power Modules providing
ing "New Telecoms" market by specifying the input
voltage range in accordance with ETSI specifica-
greater than 90% efficiency. Ericsson uses propri-
etary drive and control circuits with planar magnet-
ics and low resistivity multilayer PCB technology,
and advanced patented topology with active syn-
chronous rectification in an industry standard half
brick package with unparalleled performance.
The product features fast dynamic response times
and low output ripple, which are important param-
eters when supplying high quality DC power to
low voltage logics and Wireless applications. The
PKJ converter's excellent high efficiency and ad-
vanced design are well suited for limited board
space and high dynamic load applications.
tions. The PKJ series also offers the flexibility of
using an optional heatsink when needed, enabling
reduced airflow, extended reliability or higher ambi-
ent temperature operation. Included in the PKJ
series are over-voltage protection, under voltage
protection, over temperature protection, soft-start,
and short circuit protection.
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.
