DESCRIPTION
The VLP100xS 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 wide input
voltage ranges 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 VLP100xS's proprietary control circuitry responds
to 50-100% load steps in 100µSeconds to within 1%
nominal V
OUT
.
The patented fixed frequency architecture combined
with surface mount technology results in a compact, efficient
and reliable solution for DC/DC conversion requirements.
