DESCRIPTION

The DAC2800D series of DC-DC converters provides the

ruggedness reliability and features required to meet the ad-

vanced design challenges of today's hi-rel market. This has

beenaccomplishedwhileretainingapowerdensityof15W/

in³and 375 mW/gram of power/package performance. The

use of advanced substrate and reflow soldering techniques

during construction results in a rugged, cost-effective, and

completelysolderablepackage.

TheDAC2800Dhybridconverterseriesutilizesallceramic

capacitors, surface mount magnetics, and ultrasonically

bonded wires to provide reliable operation at all operating

temperatureswhilesurvivingGforcesofupto500G.

The DAC2800D series has two fully regulated tracking

outputs. Standard features include output fault monitoring
