The VKA100xSC Series DC/DC
converters present an economical
and practical solution for distributed
power system architectures which
require high power density and ef-
iciency 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’ tele-
communication and electronic data
processing applications. The output
is fully isolated from the input, al-
lowing for a variety of polarity and
grounding conigurations.
The VKA100xSC’s propri-
etary control circuitry responds to
50-100% load steps in 100mSeconds
to within 1% nominal Vout.
The patented ixed frequency
architecture combined with surface
mount technology results in a com-
pact, eficient and reliable solution
to DC/DC conversion requirements.
Safety Per UL1950, EN 60950 and
CSA 22.2 #234

OUTPUT ADJUST VOLTAGE
OVP NOTE
This feature allows the user to accurately adjust the module’s
output voltage set point to a speciied level. This is achieved
by connecting a resistor or potentiometer from the TRIM
terminal to either the +Vout terminal (for increased Vout) or
the -Vout terminal (for decreased Vout). The formulae below
describe the trim resistor value to obtain a Vout change of
D
%. V
O
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.
