Applying the Input
Figure 1 shows the recommended input connections for the
LV Single DC/DC converter. A fuse is recommended to
protect the input circuit and should not be omitted. The fuse
serves to prevent unlimited current from flowing in the case of
a catastrophic system failure.
Figure 1.
If the source impedance driving the LV Converter is more than 0.15
ohms the optional capacitor C2 may be required (See text for more
information). Optional transient protector diode D1 may be used if
desired for added protection. The fuse serves as a catastrophic
failure protector and should not be omitted.
When using the LV Single be sure that the impedance at
the input to the converter is less than 0.15 ohms from DC to
about 200 kHz, this is usually not a problem in battery
powered systems when the converter is connected directly to
the battery. If the converter is located more than about 1 inch
from the input source an added capacitor may be required
directly at the input pins for proper operation.
The maximum source impedance is a function of output power
and line voltage. The impedance can be higher when operating
at less than full power. The minimum impedance is
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 circuits needed, no heatsinking
problems, just “plug and play”.
The LV 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 universal 3.5 to 16 volt input allows you to specify your
system for operation from any 5 volt logic supply or a 4.8 to 12
volt nominal battery input.
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 LV converters achieve noise levels of less
than 50 mV peak to peak (S12 and S15 models) and are fully
specified and tested to a wide bandwidth of 0-20 MHz.
A water washable, non-conductive case is standard along
with specified operation over the full industrial temperature
range of -40 to +85°C case temperature.
