The DAC2800D series of DC-DC converters provides the ruggedness reliability and features required to meet the advanced design challenges of today's hi-rel market. This has been accomplished while retaining a power density W/ in3 and 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 completely solderable package. The DAC2800D hybrid converter series utilizes all ceramic capacitors, surface mount magnetics, and ultrasonically bonded wires to provide reliable operation at all operating temperatures while surviving G forces 500 G. The DAC2800D series has two fully regulated tracking outputs. Standard features include output fault monitoring and/or turn on voltage point programming via the shutdown pin. All three functions may be implemented simultaneously with a minimum of external components. An output voltage adjustment / load compensation pin which adjusts both outputs simultaneously is also standard. Fault tolerant design protects these converters from most external circuit faults. The +output and output adjust pins will withstand +25 V while the shutdown pin will withstand +50 V, protecting the converters from a variety of system or board faults e.g. solder bridges etc. Unique load fault protection circuitry allows this converter to pull up loads having difficult static load line characteristics and allows short term load excursions significantly beyond ratings in most applications. A transformer isolated flyback converter topology operating at a switching frequency of 400 kHz allows operation over a wide input voltage range. Internal filtering of outputs eliminates the need for external capacitors in many applications. The 8-pin DIP package is hermetically sealed and isolated from the internal circuits. Heat sinking is recommended for full power operation at elevated ambient temperatures. 1+OUTPUT OUTPUT COMMON -OUTPUT ADJUST/COMP SHUTDOWN PLUS 7 6 CASE -INPUT +INPUT
