TYPICAL APPLICATION
DESCRIPTION
The DAC2812S and DAC2815S DC-DC converters are
higher output voltage companion devices to MSK's DHC
types. The DAC's provide the ruggedness, reliability and
features required to meet the advanced design challenges of
today's hi-rel market. This has been accomplished while
retaining a power density of 15 W/in3 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 DAC2800S hybrid converter series utilizes all ceramic
capacitors, surface mount magnetics, and ultrasonically bonded

wires to provide reliable operation at all operating tempera-

tures while surviving G forces of up to 500 G.
The DAC2800S series 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

Fault tolerant design protects these converters from most
external circuit faults. The +output and output adjust pins will

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.
EXTERNAL CONNECTIONS
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 eliminates
the need for external capacitors in many applications.
The 8-pin package is hermetically sealed and isolated from
the internal circuits. Heat sinking is recommended for full
power operation at elevated ambient temperatures.
