Input Fusing
Certain applications and/or safety agencies may require the installation of
fuses at the inputs of power conversion components. For MPS A-Series
BWR 7-10 Watt DC/DC Converters, you should use slow-blow type fuses
with values no greater than the following:
VIN Range
"D5A"
"D12A"
"D48A"
Fuse Value
3A
2A
1A

effective power converters available.
EMI RADIATED EMISSIONS
If you’re designing with EMC in mind, please note that all of MPS’s BWR
7-10 Watt A-Series DC/DC Converters have been characterized for radi-
ated and conducted emissions in our new EMI/EMC laboratory. 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 specifica-
tions can be supplied upon request. Radiated emissions plots to FCC and
CISPR 22 for model BWR-15/330-D48A appear below. Published EMC test
reports are available for each model number. Contact MPS’s Applications
Engineering Department for more details.
