The PKL 4000 series represents another one of
Ericsson's "industry first" achievements in the con-
tinuing development of our "Third Generation" of
high-density, high-efficiency power modules. The
PKL 4110A PI module packs 68W/in
3
at 92%
efficiency (3.3V @ 60A) in an half-brick footprint
that has been enhanced to include two additional
output pins for motherboard connection reliability at
this high power.
These breakthrough features come from using the
most advanced patented topology utilizing inte-
grated magnetics and synchronous rectification on a
low-resistivity multilayer PCB.
This product features fast dynamic response times
and low output ripple, which are important
parameters when supplying low-voltage logics.
The PKL 4000 PI Series also is especially well suited
for limited board space and high dynamic load
applications.
Ericsson's PKL 4000 Series Power Modules address
the converging "New Telecom" market, by specifying
the input voltage range in accor-dance with ETSI
specifications. The PKL 4000 Series also offers over-
voltage protection, under-voltage protection, over-
temperature protection, soft-start, paralleling, and
short circuit protection.
These modules are manufactured on highly
automated manufacturing lines. Ericsson's world-
class quality commitment is reflected in our standard
five year warranty. Ericsson Inc.,
Power Modules
has been an ISO 9001 certified Suplier since 1991.

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.
