Since these are isolated DC/DC converters, their outputs are "floating." Any
BWR model may be conꢀgured 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 6 and 8), with either output grounded.
The Common (pins 5 and 7) should be left open. Minimum 20% loading is
recommended under these conditions.

All BWR 3 Watt DC/DC Converters achieve their rated ripple and noise
speciꢀcations without the use of external input/output capacitors. In critical
applications, input/output ripple and noise may be further reduced by install-
ing electrolytic capacitors across the input terminals and/or low-ESR tanta-
lum or electrolytic capacitors across the output terminals. Output capacitors
should be connected between their respective output pin (pin 6 or 8) and
Common (pins 5 and 7) 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.

Non RoHS: Tin plate over copper alloy

➀ These power converters require a minimum 10% loading to maintain speciꢀed regulation.
Operation under no-load conditions will not damage these devices; however they may not
meet all listed speciꢀcations.
➁ Application-speciꢀc internal input/output ꢀltering can be recommended and perhaps added
internally upon request. Contact DATEL Applications Engineering for details.
➂ Devices can be screened or modiꢀed for higher guaranteed isolation voltages.
Contact DATEL Applications Engineering for details.
➃ Devices can be warranted or screened for lower-temperature operation.
Contact DATEL Applications Engineering for details. See DATEL's new BST 3W Models
for guaranteed operation to –40°C.

If you’re designing with EMC in mind, note that all of DATEL’s BWR 3 Watt
DC/DC Converters have been characterized for radiated and conducted
emissions in our new EMI/EMC laboratory. Testing is conducted in an EMCO
5305 GTEM test cell utilizing EMCO automated EMC test software. Radi-
ated emissions are tested to the limits of FCC Part 15, Class B and CISPR
22 (EN 55022), Class B. Correlation to other speciꢀcations can be supplied
upon request. Radiated emissions plots to FCC and CISPR 22 for model
BWR-5/250-D12 appear below. Published EMC test reports are available for
each model number. Contact DATEL’s Applications Engineering Department
for more details.
