The VKQ100MS3V3 DC/DC
converter presents an economical and
practical solution for distributed power
system architectures which require high
power density and efficiency while
maintaining system modularity and
upgradeability. With the ability to operate
over a wide input voltage range of 36 to
75 Vdc, this module is ideal for
telecommunications and battery backup
applications where input flexibility must
be combined with output voltage
regulation. In addition, the output is fully
isolated from the input, allowing for a
variety of polarity and grounding
configurations.
Innovative circuit design using
surface mount components results in a
compact, efficient and reliable solution to
DC/DC conversion needs. Internal power
dissipation is minimized by the
VKQ100MS3V3’s high efficiency and is
aided by a metal baseplate to which all
heat dissipative elements are coupled.
The control circuitry of the
VKQ100MS3V3 has been designed to
provide overvoltage protection as well as
current limiting for continuous short-
circuit protection. The VKQ100MS3V3
is operation specified from rated load to
zero load.
