The proven cost-effectiveness, quality and long-term reliability that has come to
define DATEL’s standard, 3W, dual-output, DIP-packaged DC/DC converters (see
BST 3W Models) is now available in the "other standard pinout" (see next page)
made popular by off-shore suppliers. These newly designed BWP Models exploit
totally automated SMT assembly techniques and do not contain any trimpots, "wet"
aluminum electrolytic capacitors, or manually soldered "flying" leads. Their made-in-
the-USA quality and affordable pricing are rapidly making them the converters of
choice in many existing applications.
BWP DC/DC converters bring true component-like convenience to designers of
modern distributed power systems. Exploiting an efficient, high-frequency (170-
200kHz), flyback topology and high-density SMT assembly techniques, BWP DC/
DC’s have enough space to include input (pi type) and output filters within their
package. They are fully isolated (500Vdc guaranteed) and do not require any
external components to meet published specifications. They operate, without
derating, over the full –40 to +75°C temperature range.
Output voltages are either ±5, ±12 or ±15 Volts. Input voltage ranges are either
4.5-9V ("D5" models), 9-18V ("D12" models) or an ultra-wide 18-72V ("D48"
models). Output transient response time is a quick 200µsec, and output ripple and
noise are typically 75mVp-p. All models are certified to UL1950, CSA 22.2 No. 950
and IEC950. Full EMI/EMC characterizations are currently in progress.
DATEL’s BWP Model 3W DC/DC’s are ideal replacements for other more costly,
less reliable power converters as well as excellent choices for new design-ins in
systems demanding small size, low cost and high reliability.

Since these are isolated DC/DC converters, their outputs are "floating." Any
BWP 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 (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
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 (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.

➀
These power converters require a minimum 10% loading to maintain specified regulation.
Operation under no-load conditions will not damage these devices; however they may not
meet all listed specifications.
➁
Application-specific internal input/output filtering can be recommended and perhaps added
internally upon request. Contact DATEL Applications Engineering for details.
➂
Devices can be screened or modified for higher guaranteed isolation voltages.
Contact DATEL Applications Engineering for details or see DATEL's BST 3W DC/DC's
for guaranteed 1000Vdc isolation.
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.
