The migration to distributed power is accelerating. The critical need f or 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 f eatured, 5 W att UWR Models were specifically designed for
today’s demanding distributed po wer architectures in aerospace, marine, telecom and
computer applications. The conv erters' low cost, small size (1" x 1" x 0.45") and full 5
Watt output capability give system architects unprecedented design and la yout flexibility.

total volume, these extremely compact, fully regulated
and isolated (1000Vdc guaranteed) modules are available with either 5, 12 or 15 V olt
outputs. Input voltage ranges are either 18-36 Volts ("D24" models) or 36-72 V olts ("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 W att modules. They achiev e 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 pc­card 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 electrically tested before and after encapsulation, 100% burned­in under full load, hi-pot tested, and final-electrical tested prior to shipment. Every unit
meets DATEL’s traditional high standards f or quality and long-term reliability .
