MSK - DAC2800D series

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

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
