These converters require a minimum 20% loading on each output to maintain specified
regulation. Operation under no-load conditions will not damage these devices; however
they may not meet all listed specifications.
Application-specific internal input/output filtering can be recommended and perhaps added
Applying a voltage to the Control pin when no input power is applied to the converter can
cause permanent damage to the converter.
"D48A" models have BASIC, "D5A" and "D12A" models have Functional insulation.
Devices can be screened or modified for higher guaranteed isolation voltages.

Floating Outputs
Since these are isolated DC/DC converters, their outputs are "floating." Any
BWR model may be configured to produce an output of 10V, 24V or 30V
(for
the +Output and –Output pins (pins 5 and 7), with either output grounded.
The Common pin (pin 6) should be left open. Minimum 20% loading is
recommended under these conditions. The total output voltage span may be
externally trimmed as described below.
Filtering and Noise Reduction
All A-Series BWR 15-20 Watt DC/DC Converters achieve their rated ripple
and noise specifications without the use of external input/output capacitors.
In critical applications, input/output ripple and noise may be further reduced
by installing electrolytic capacitors across the input terminals and/or low-ESR
tantalum or electrolytic capacitors across the output terminals. Output capac-
itors should be connected between their respective output pin (pin 5 or 7) and
Common (pin 6) as shown in Figure 2. The caps should be located as close
to the power converters as possible. Typical values are listed in the tables
below. In many applications, using values greater than those listed will yield
better results.

These are stress ratings. Exposure of devices to greater than any of these conditions may
adversely affect long-term reliability. Proper operation under conditions other than those
listed in the Performance/Functional Specifications Table is not implied.
