migration distributed power accelerating. critical need accurate voltages, tight regulation rapid transient response propelling move power processing "point-of-use" with low-power DC/DC converters physically located right their loads. DATEL's miniature, full featured, Watt Models were specifically designed today's demanding distributed power architectures aerospace, marine, telecom computer applications. converters' small size 0.45"), full Watt output capability cost give system architects unprecedented design layout flexibility. Occupying less than 0.5in3 total volume, these extremely compact, fully regulated isolated (1000Vdc) modules available with Volt outputs. Input voltage ranges either 18-36 Volts ("D24" models) 36-72 Volts ("D48" models). Although their overall size 50-75% smaller than many similarly rated power modules, these Models exact, drop-in, pin-for-pin replacements many standard Watt modules. They achieve their small size cost exploiting novel feedback approach that does depend upon traditional optocoupler techniques. models 5-side shielded have non-conductive baseplate that permits pc-card runs placed beneath package. Units assembled using high-speed automated techniques fully encapsulated with thermally conductive potting compound. Every unit electrically tested before after encapsulation, 100% burned-in under full load, hi-pot tested, final-electrical tested prior shipment. Every unit meets DATEL's traditional high standards quality long-term reliability.
