MIL-PRF-38534 CERTIFIED
4707 Dey Road Liverpool, N.Y. 13088
FEATURES:
DESCRIPTION:
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
substrate and reflow soldering techniques during construction results in a rugged, cost-effective and
completely solderable package.
ultrasonically bonded wires to provide reliable operation at all operating temperatures.
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.
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.

capacitors in many applications.
recommended for full power operation at elevated ambient temperatures.
