The VKA75xSC 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 applica-

tions. The output is fully isolated from the input, allowing for a variety of polarity and grounding

configurations.

The VKA75xSC’s proprietary control circuitry responds to 50-100% load steps in 100mSec-

onds 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.

PRODUCT SELECTION CHART

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.
