The VKA150MS24-205C DC/DC converter presents 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, this module is 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 VKA150MS24-205’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. Safety approvals per UL/CUL 1950, EN 60950.

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.
Radj - up =
( Vo(100 + Δ%)
Radj - down =
1.225Δ%
(100 Δ- %2)
_
)
(100 + 2Δ%) Ω
Δ%
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.
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.
