The use of advanced substrate and reflow soldering techniques during construction results in a rugged, cost-effective and completely solderable package. DHD2805S hybrid converter utilizes all ceramic capacitors and surface mount magnetics to provide reliable operation at all operating temperatures while surviving very high G forces. DHD2805S 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 is also standard. Fault tolerant design protects these converters from most external circuit faults. The output and output adjust pins will withstand +35V while the shutdown pin will withstand +50V protecting the converters from a variety of system or board faults i.e. 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 forward converter topology operating at a switching frequency of 400kHz allows operation over a wide input voltage range. Internal filtering of both input and output 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 Rev.
