DESCRIPTION:
The DAC2812D and DAC2815D DC-DC converters 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 DAC2800D hybrid converter series utilizes all ceramic capacitors, surface mount magnetics, and
ultrasonically bonded wires to provide reliable operation at all operating temperatures.
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 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.
