PRODUCT OVERVIEW
■
Low
The proven cost-effectiveness, quality and
long-term reliability that has come to define
Murata Power Solutions' standard, 3W, dualoutput, 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 componentlike 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
cost! High quality!

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.
MPS’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.
Typical topology is shown.

Floating Outputs
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.
To Reduce Input Ripple
"D5" Models
47μF, 15V
"D12" Models
10μF, 35V
"D48" Models
4.7μF, 100V
To Reduce Output Ripple
±5V Outputs
47μF, 10V, Low ESR
±12/15V Outputs
22μF, 20V, Low ESR
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.
