The VKA100xSC Series DC/DC con-
verters present an economical and
practical solution for distributed power
system architectures which require
backup applications common in today’s
telecommunication and electronic data
processing applications. The output is
fully isolated from the input, allowing
The patented fixed frequency
architecture combined with surface
mount technology results in a compact,
efficient and reliable solution to DC/
DC conversion requirements. Safety Per

high power density and efficiency while for a variety of polarity and grounding
maintaining system modularity and
upgradeability. With the ability to oper-
ate over a wide input voltage range
of 18 to 36 and 33 to 75 volts, these
modules are ideal for use in battery
configurations.
The VKA100xSC’s proprietary con-
trol circuitry responds to 50-100% load
steps in 100mSeconds to within 1%
nominal Vout.

OUTPUT ADJUST VOLTAGE
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 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
Δ%. 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.
