The VKQ100MS05 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
VKQ100MS05’s high efficiency and is
aided by a metal baseplate to which all
heat dissipative elements are coupled.
The control circuitry of the
VKQ100MS05 has been designed to
provide overvoltage protection as well as
current limiting for continuous short-
circuit protection.
