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/

in³and 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.
