Artesyn Embedded Technologies ADQ800 800W Quarter Brick DC-DC Converter

Artesyn Embedded Technologies ADQ800 Quarter-Brick Isolated DC-DC Converter produces a single fully regulated 11.8V output. Rated at 800W, the converter can deliver up to 70A output current and has no minimum load requirement. This device has an input voltage range of 40V to 60V and is primarily designed for use with standard 48V supplies in computing and server applications, and regulated 48V supplies in communications equipment. The ADQ800-48S12B-4L is a low-profile unit that is an ideal choice for demanding inter-board spacing requirements as the baseplate version requires only 0.53" (13.6mm). 

The ADQ800-48S12B-4L has an ultra-high efficiency of typically 96% at full load and can operate over an ambient temperature range of -40°C to +85°C. These features make it an ideal choice for the isolated converter in a distributed power architecture supplying power to non-isolated converters. An aluminum baseplate structure is available for enhanced thermal performance.

ADQ800-48S12B-4L has an enhanced pre-bias start-up capability and for high current applications, two converters can be connected in parallel, automatically using the droop method of current sharing.
