Miniature 5 Watt DC-DC Converters
Typical units
FEATURES
PRODUCT OVERVIEW
The migration to distributed power is accelerating.
The critical need for accurate voltages, tight regu-
lation and rapid transient response is propelling
the move to power processing at the "point-of-
use" with low-power DC-DC converters physically
located right at their loads.
Although their overall size is 50-75% smaller than
many similarly rated power modules, these 1"
x 1" BWR Models are exact, drop-in, pin-for-pin
replacements for many standard 2" x 1" and 2"
x 2", 5 Watt modules. They achieve their small
size and low cost by exploiting a novel feedback
approach that does not depend upon traditional
optocoupler techniques.
Small size, 1" x 1" x 0.45"
Full 5 Watts output power
No external components required
Drop-in replacements for many standard,
2" x 1" DC-DCs
Wide input voltage ranges:
18-36V or 36-72V
MPS’s miniature, full featured, 5 Watt BWR Models
were specifically designed for today’s demand-
ing distributed power architectures in aerospace,
marine, telecom and computer applications. The
converters’ small size (1" x 1" x 0.45"),
full 5 Watt output capability and low cost give
system architects unprecedented design and
layout flexibility.
Occupying less than 0.5in3 total volume, these
extremely compact, fully regulated and isolated
(1000Vdc) modules are available with 5, 12 or
15 Volt outputs. Input voltage ranges are either
18-36 Volts ("D24" models) or 36-72 Volts ("D48"
models).
All models are 5-side shielded and have a non-
conductive baseplate that permits pc-card runs
to be placed beneath the package. Units are
assembled using
high-speed automated SMT techniques and are
fully encapsulated with thermally
conductive potting compound. Every unit is electri-
cally tested before and after
encapsulation, 100% burned-in under full load,
hi-pot tested, and final-electrical tested prior to
shipment. Every unit meets MPS’s traditional high
standards for quality and long-term reliability.

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 3 and 6), with either output grounded. The
Common (pin 4) should be left open. Minimum 20% loading is recom-
mended under these conditions.

Filtering and Noise Reduction
Case Connection:
"D24" Models
"D48" Models
All BWR 5 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 install-
ing low-ESR, tantalum or electrolytic capacitors across the input
and/or output terminals. Output capacitors should be connected between
their respective output pin (pin 3 or 6) and Common (pin 4) as shown in
Figure 2. The capacitors should be located as close to the power convert-
ers as possible. Typical values are listed below. In many applications, using
values greater than those listed will yield better results.

If you’re designing with EMC in mind, all MPS’s BWR 5 Watt DC-DC's have
been characterized for radiated/conducted emissions in our new EMI/EMC
lab. Testing is conducted in an EMCO 5305 GTEM test cell utilizing EMCO
automated EMC test software. Radiated emissions are tested to the limits
of FCC Part 15, Class B and CISPR 22 (EN 55022) Class B. Correlation to
other specifications can be supplied upon request. Radiated emissions plots
to FCC and CISPR 22 appear below. Its performance is typical of all models
in the Family. Published EMC test reports are available for each model
number. Contact MPS’s Applications Engineering Department for details.
