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/
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 DAC2800S hybrid converter series utilizes all ceramic capacitors, surface mount magnetics, and
ultrasonically bonded wires to provide reliable operation at all operating temperatures.
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 output voltage adjustment / load compensation pin which adjusts outputs
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 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.
