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. This is
accomplished while retaining a power density of 17 W/in
3
and
425 mW/gram of power/package performance. The use of
advanced substrate and reflow soldering techniques during
construction results in a rugged, cost-effective, and com-
pletely 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 monitor-
ing and/or turn on voltage point programming via the shut-
down pin. All three functions may be implemented simulta-
neously 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 +35 V while the shutdown pin will withstand +50 V
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 operat-
ing at a switching frequency of 400 kHZ 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.
