ing. The critical need for accurate voltages, tight
regulation and rapid transient response is propel-
ling the move to power processing at the "point-of-
use" with low-power DC/DC converters physically
located right at their loads.
Models were specifi cally designed for today’s
demanding distributed power architectures in
aerospace, marine, telecom and computer applica-
tions. The converters' low cost, small size (1" x
1" x 0.45") and full 5 Watt output capability give
system architects unprecedented design and layout
fl exibility.
extremely compact, fully regulated and isolated
(1000Vdc guaranteed) modules are available with
either 5, 12 or 15 Volt outputs. Input voltage ranges
are either 18-36 Volts ("D24" models) or 36-72
Volts ("D48" models).

... Filtering and Noise Reduction All UWR 5 Watt DC/DC Converters achieve their rated ripple and noise specifi cations without the use of external input/output capacitors. In criti- cal applications, input/output ripple and noise may be further reduced by installing low-ESR, tantalum or electrolytic capacitors across the input and/or output terminals ...
