DESCRIPTION
The VKA100xS Series DC/DC converters present 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 18 to 36 and 33 to 75 volts, these
modules are ideal for use in battery backup applications
common in todays' telecommunication and electronic
data processing applications. The output is fully isolated
from the input, allowing for a variety of polarity and
grounding configurations.
The VKA100xS's proprietary control circuitry responds
to 50-100% load steps in 100
μ
Seconds to within 1%
nominal Vout.
The patented fixed frequency architecture combined with
surface mount technology results in a compact, efficient
and reliable solution to DC/DC conversion requirements.
