310W DC/DC Power Module
48V Input, 28.2V Output
Ericsson's28 volt PKL 4316 PIT Power Module has
been designed with the global wireless Telecomm
market in mind, by specifying the input voltage
range in accordance with ETSI specifications.
These modules are manufactured on highly
automated manufacturing lines. Ericsson's world-
class quality commitment is reflected in our
standard five year warranty. Ericsson
Microelectronics has been an ISO 9001 certified
Supplier since 1991.
For a complete product program, please reference the back
cover.

Low Output Ripple, 50 mVp-p Typ.
The PKL 4000 series represents another one of
Ericsson's "industry first" achievements in the
continuing development of our "Third Generation"
of high-density, high-efficiency power modules.
The PKL 4316 PIT module packs 106.7 W/in
3
at
91% efficiency (28.2V @ 11A) in an industry
standard footprint. The PKL 4000 package has
been enhanced to include two additional output
pins for motherboard connection reliability at this
high power.
This product features fast dynamic response times
and low output ripple, which are important
parameters when supplying high quality DC power
to wireless applications. The PKL 4000 Series also
is especially well suited for limited board space and
high dynamic load applications.

Absolute Maximum Ratings
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.
