Floating Outputs
Since these are isolated DC/DC converters, their outputs are "oating." Any
BMP model may be congured to produce an output of 10V, 24V or 30V (for
±
5V, ±12V or ±15V models, respectively) by applying the load across the
+Output and –Output (pins 9 and 6), with either output grounded. The Com-
mon (pin 8) should be left open. Minimum 20% loading is recommended
under these conditions. The total output voltage span may be externally
trimmed as described below.

These converters require a minimum 10% loading on each output to maintain
specied regulation. Operation under no-load conditions will not damage these devices;
however they may not meet all listed specications.
"Full load" varies by part number and is determined by the input voltage range as indi
cated by the part number sufx. See Technical Notes and Output Power Considerations.
Application-specic input/output ltering can be recommended or perhaps added inter
nally 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 con
verter can cause permanent damage to the converter.
Listed specication is for input-to-output isolation. Input-to-case and output-to-case
isolation is 1000Vdc, minimum.
Filtering and Noise Reduction
All BMP 25-40 Watt DC/DC Converters achieve their rated ripple and noise
specications without the use of external input/output capacitors. In criti-
cal 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.

"Q12, D24" Models
47μF, 50V
"Q48, D48" Models

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 Specications Table is not implied.
