The PKV series of DC/DC power modules is intended
for general use in 12/24 V and 48/60V DC systems.
Designed with MOSFET transistors and 200 kHz
switching frequency, they are characterized by high
efficiency over a wide load range, very low quiescent
power and an excellent line and load regulation.
The DC/DC power modules are encapsulated in an
epoxy filled plastic box. The flammability ratings of
the encapsulating materials are in conformance with
UL 94V-0 and have an adequate thermal conductivity.
The materials withstand all normal PBA cleaning
methods.
Ericsson Microelectronics AB has been an ISO 9001
certified supplier since 1991.

Absolute Maximum Ratings
Power Derating
These DC/DC power modules operate
without any external components.
However, in low noise applications it is
recommended to use a filter. Please see
EMC information included in this data
sheet.
It is recommended to protect the input
source by fuses or other protection de-
vices. Fuses are not supplied internally.
A slow fuse with rating of 2 the I
Imax
is
recommended.
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.
