The PKB series of high efficiency DC/DC converters are
designed to provide high quality on-board power solu-
tions in distributed power architectures used in Internet-
working equipment in wireless and wired communications
applications . The PKB 4000 series has industry standard
footprint and pin-out and is max 8 .10 mm (0 .319 in) high .
This makes it extremely well suited for narrow board pitch
applications with board spacing down to 15 mm (0 .6 in) .
Included as standard features are output over-voltage
protection, input under-voltage protection, over tempera-
ture protection, soft-start, output short circuit protection,
remote sense, remote control and output voltage adjust
function .
These converters are designed to meet high reliability
requirements and are manufactured in highly automated
manufacturing lines and meet world-class quality levels .
Ericsson Power Modules is an ISO 9001/14001 certified
supplier .

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 .
