Performance/Functional Specications
Typical @ TA = +25°C under nominal line voltage and full-load conditions unless noted.
T E C H N I C A L N O T E S
These power converters require a minimum 10% loading to maintain specied regulation.
Operation under no-load conditions will not damage these devices; however they may not
meet all listed specications.
Application-specic internal input/output ltering can be recommended and perhaps
added internally upon request. Contact DATEL Applications Engineering for details.
Devices can be screened or modied for higher guaranteed isolation voltages.
Contact DATEL Applications Engineering for details or see DATEL's BST 3W DC/DC's
for guaranteed 1000Vdc isolation.

Input Reverse-Polarity Protection
Current must be <2A. Brief duration
only. Fusing recommended.
Output Overvoltage Protection
None
Output Current
Current limited. Max. current and
short-circuit duration are model
dependent. “D12” and “D48”
models
can withstand
sustained output short
circuits.
Storage Temperature
–55 to +100°C
Lead Temperature (soldering, 10 sec.)
+280°C
These are stress ratings. Exposure of devices to 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.
Absolute Maximum Ratings
Floating Outputs
Since these are isolated DC/DC converters, their outputs are "oating." Any
BWP 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 (pins 11 and 14) and –Output pins (pins 2 and 23), with either
output grounded. The Common (pins 3, 10,15 and 22) should be left open.
Minimum 20% loading is recommended under these conditions.
Filtering and Noise Reduction
All BWP 3 Watt DC/DC Converters achieve their rated ripple and noise speci-
cations without the use of external input/output capacitors. In critical ap-
plications, 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 (pins 2, 11, 14 and 23)
and Common (pins 3, 10, 15 and 22) 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.
To Reduce Input Ripple
"D5" Models
47F, 15V
"D12" Models
10F, 35V
"D48" Models
4.7F, 100V
To Reduce Output Ripple
±5V Outputs
47F, 10V, Low ESR
±12/15V Outputs
22F, 20V, Low ESR
In critical, space-sensitive applications, DATEL may be able to tailor the in-
ternal input/output ltering of these units to meet your specic requirements.
