Features

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.

DA TEL’s miniature, full f eatured, 5 W att BWR Models were specifically designed for
today’s demanding distributed po wer architectures in aerospace, marine, telecom and
computer applications. The con verters’ small size (1" x 1" x 0.45"),
full 5 Watt output capability and low cost give system architects unprecedented design
and layout flexibility.

Occupying less than 0.5in

total volume, these extremely compact, fully regulated
and isolated (1000Vdc) modules are available with ±5, ±12 or ±15 V olt outputs. Input
voltage ranges are either 18-36 V olts ("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" BWR 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
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 final­electrical tested prior to shipment. Every unit meets DA TEL’s traditional high standards
for quality and long-term reliability .
