5 Watt, DC/DC Converters
The migration to distributed power is accelerating. The critical need for accurate
voltages, tight regulation 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.
DATEL’s miniature, full featured, 5 Watt UWR Models were specifically designed
for today’s demanding distributed power architectures in aerospace, marine, telecom
and computer applications. 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
flexibility.
Occupying less than 0.5in3 total volume, these 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).
Although their overall size is 50-75% smaller than many similarly rated power
modules, these 1" x 1" UWR 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.
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 highspeed automated SMT techniques and are fully encapsulated with thermally conductive potting compound. Every unit is electrically tested before and after encapsulation,
100% burned-in under full load, hi-pot tested, and final-electrical tested prior to shipment. Every unit meets DATEL’s traditional high standards for quality and long-term
reliability.
