The VKA60xSC 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 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 VKA60xSC’s proprietary
control circuitry responds to 50-100%
load steps in 100MSeconds to within 1%
nominal Vout.

THROUGH-HOLE SOLDERING INFORMATION
These devices are intended for wave soldering or manual soldering.
They are not intended to be subject to surface mount processes under any circumstances.
The normal wave soldering process can be used with these devices where the device is subjected to a maximum wave temperature of 260°C for a period of
no more than 10 seconds. Within this time and temperature range, the integrity of the device’s plastic body will not be compromised and internal temperatures
within the converter will not exceed 175°C. Care should be taken to control manual soldering limits identical to that of wave soldering.

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
$%. VO is output voltage prior to adjustment (3.3V, 5V, 12V,
15V, or 24V).
Radj - up =
(
Radj - down =
Vo(100 + $%) _ (100 + 2$%)
1.225$% $%
(100 $-%2)
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.
