DESCRIPTION
The VKA150MS 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 33 to 75 volts, these modules are
ideal for use in battery backup applications common in
todays' telecommunication and electronic data process-
ing applications. The output is fully isolated from the
input, allowing for a variety of polarity and grounding
configurations.

The VKA150MS's proprietary control circuitry responds
to 50-100% load steps in 100µSeconds 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.

MATERIAL: Units are encapsulated in a low thermal
resistance molding compound which has excellent
chemical resistance and electrical properties in high
humidity environments and over a wide operating
temperature range. The encapsulant and outer shell of
the unit have UL94V-0 ratings. Lead material is solder
plated to allow ease of solderability.

OUTPUTVOLTAGE ADJUST
OVP NOTE
This feature allows the user to accurately adjust the
module's output voltage set point to a specified level.
This is achieved by connecting a resistor or potentiom-
eter from the TRIM terminal to either the +Vout termi-
nal (for increased Vout) or the -Vout terminal (for
decreased Vout). The formulae below describe the trim
resistor value to obtain a Vout change of ∆%. VO is
output voltage prior to adjustment (3.3V, 5V, 12V, 15V
or 24V).
Special attention should be given to the peak voltage
deviation during a dynamic load step when trimming
the output above the original set point to avoid tripping
the overvoltage protection circuit. Should an OVP
condition occur, the converter will go into a latch
condition and must be externally reset before it will
return to normal operation.
