The PKM 4000C series of high efficiency DC/DC
converters are designed to provide high quality on-board
power solutions in distributed power architectures used
in Internetworking equipment in wireless and wired
communications applications.
The PKM 4000C series features a "double-p" footprint
with dual output pins which reduces soldering losses to
the board while increasing the cooling of the module.
The PKM 4000C series uses patented synchronous
rectification technology and achieves an efficiency up to
90% at full load.
Included as standard features are output over-voltage
protection, input under-voltage protection, over temperature
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.

PKM 4110C PIPNB
PKM 4110C PINBLA
PKM 4110C PINBSP
Note: As an example a positive logic and short pin product would be PKM 4110C PINBLA.
*A single pin option is available but will decrease the maximum available output current.
Ericsson power modules do not recommend that each pin should conduct more than 40A due
to power dissipation inside the pin and the board.
To use more current than stated will have impact on solder joints and current distribution to
the board, the power module will however be safe but will have more power dissipation due to
less conductive material to the board.

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.
