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
been accomplished while retaining a power density of 15 W/
in
3
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 of up to 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 out-
puts 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 elimi-
nates 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.
