Maximum Case Temperature
These converters require a minimum 10% 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.
"Full load" varies by part number and is determined by the input voltage range as indicated by
the part number suffix. See Technical Notes and Output Power Considerations.
Application-specific input/output filtering can be recommended or perhaps added internally
upon request. Contact DATEL Applications Engineering for details.
Applying a voltage to the On/Off Control pin when no input power is applied to the converter
can cause permanent damage to the converter. If desired, the On/Off Control function can be
replaced with a Sync function. See page 6 of this data sheet for more details.
Listed specification is for input-to-output isolation. Input-to-case and output-to-case
isolation is 1000Vdc, minimum.

Floating Outputs
Since these are isolated DC/DC converters, their outputs are "floating." Any
BMP model may be configured to produce an output of 10V, 24V or 30V (for
±
+Output and –Output (pins 9 and 6), with either output grounded. The
Common (pin 8) should be left open. Minimum 20% loading is recom-
mended under these conditions. The total output voltage span may be
externally trimmed as described below.
Filtering and Noise Reduction
All BMP 25-40 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
capacitors should be connected between their respective output pin (pin 6 or
9) and Common (pin 8). See Figure 7. The caps should be located as close
to the converters as possible. Typical values are listed in the below. In many
applications, using values greater than those listed will yield better results.
In critical, space-sensitive applications, DATEL may be able to tailor the
internal input/output filtering of these devices to meet your specific require-
ments. Contact our Applications Engineering Group for additional details.
