The VSX50 Series are 50 Watt, compact,
high-efficiency, high-density dual output
converters with a 36-75V input and
2.5Vdc and 3.3Vdc outputs. The industry
quarter-pack size of 2.3" x 1.5" x 0.5"
coupled with 89% efficiency is an
industry high-density breakthrough.
These converters utilize V Series high
density technology. This technology has
been featured in our highly efficient VKP
and VKA Series now successfully in use
worldwide. The very high 89%
efficiency minimizes the requirement for
heat-sinking and the low output ripple
minimizes the need for additional
filtering. For maximum flexibility, power
can be traded between outputs as
required. The VSX50 Series feature
virtually all of the options required by
design engineers but not at the
competition鈥檚 typical additional price
for each option. This multitude of
features are standard on the VSX50
Series.
