DHC2800S

DESCRIPTION:

The DHC2800S series of DC-DC converters provides the ruggedness, reliability and features required to

meet the advanced design challenges of today's hi-rel market. The use of advanced substrate and reflow

soldering techniques during construction results in a rugged, cost-effective and completely solderable package.

DHC2800S hybrid converter series utilizes all ceramic capacitors and surface mount magnetics to

provide reliable operation at all operating temperatures while surviving very high G forces.

DHC2800S 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.
