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 specifi cations 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.

Input Fusing
Certain applications and/or safety agencies may require the installation of
fuses at the inputs of power conversion components. For MPS BWR
5 Watt DC-DC Converters, you should use slow-blow type fuses with values
no greater than 0.5A.
MPS’s world-class design, development and manufacturing team stands
ready to work with you to deliver the exact power converter you need for
your demanding, large volume, OEM applications. And . . . we’ll do it on time
and within budget!
Our experienced applications and design staffs; quick-turn prototype
capability; highly automated, SMT assembly facilities; and in-line SPC
quality-control techniques combine to give us the unique ability to design
and deliver any quantity of power converters to the highest standards of
quality and reliability.
We have compiled a large library of DC-DC designs that are currently used
in a variety of telecom, medical, computer, railway, aerospace and industrial
applications. We may already have the converter you need.
Contact us. Our goal is to provide you the highest-quality, most cost-effective
power converters available.
