ΠThese 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

internally upon request. Contact DATEL Applications Engineering for details.

Ž Applying a voltage to the Control pin when no input power is applied to the converter can

cause permanent damage to the converter.

 Devices can be screened or modified for higher guaranteed isolation voltages.

TECHNICAL NOTES

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

±5V, ±12V or ±15V models, respectively) by applying the load across 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

capacitors 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.

In critical, space-sensitive applications, DATEL may be able to tailor the

internal input/output filtering of these units to meet your specific require-

ments. Contact our Applications Engineering Group for additional details.
