The PKJ series represents a "third generation" of
High Density DC/DC Power Modules providing
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.

Ericsson's PKJ Power Modules address the converg-
ing "New Telecoms" market by specifying the input
voltage range in accordance with ETSI specifica-
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.

Absolute Maximum Ratings Typical Characteristics
Output
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.
