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/in3 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.
