Application Information
You truly get what you pay for in a CALEX converter, a
complete system oriented and specified DC/DC converter -
no surprises, no external noise filtering circuits needed, no
heatsinking problems, just
“
plug and play
”
.
The 45 watt XT Single series like all CALEX converters
carries the full 5 year CALEX no hassle warranty. We can offer
a five year warranty where others can
’
t because with CALEX
it
’
s rarely needed.
Keep reading, you
’
ll find out why.
General Information
The XT Single series is mindful of battery operation for
industrial, medical control and remote data collection
applications. The remote ON/OFF pin places the converter in
a very low power mode that draws typically less than 10 mA
from the input source.

Noise has also achieved new lows in this single design,
while the industry standard is to specify output noise as 1 to
5% peak to peak typical with no mention of measurement
bandwidth. The XT converters achieve 50 mV peak to peak
typical and are fully specified and tested to a wide bandwidth
of 0-20 MHz.
Input filtering reduces reflected ripple noise and is similarly
low and also fully specified for typical values (exact value
depends on input voltage range). Typical RMS noise over a 10
kHz to 1 MHz bandwidth is specified for both the input and
output.
Full overload protection is provided by independent pulse-
by-pulse current limiting and an over-temperature shutdown
circuit. These protection features assure you that our XT
single will provide you with zero failure rate operation.
Five sided shielding is standard along with specified operation
over the full industrial temperature range of -40 to +85
