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 BWR Models were specifically designed
for today’s demanding distributed power architectures in aerospace, marine,
telecom and computer applications. The converters’ 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 0.5in3 total volume, these extremely compact, fully regulated
and isolated (1000Vdc) modules are available with ±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" BWR 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
high-speed 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.
