GENERAL DESCRIPTION
The ADDC02805S hybrid dc/dc converter with integral EMI
filter offers the highest power density of any dc/dc converter
with its features and in its power range available today. The
converter with integral EMI filter is a fixed frequency, 1 MHz,
square wave switching dc/dc power supply. It is not a variable
frequency resonant converter. In addition to many protection
PRODUCT HIGHLIGHTS
1. 60 W/cubic inch power density with an integral EMI filter
designed to meet all applicable requirements in MIL-STD-
461D when installed in a typical system setup.
2. Light weight: 80 grams
3. Operational and survivable over a wide range of input
features, this converter has system level features that allow it to
conditions: 16 V–50 V dc; survives low line, high line, and
be used as a component in larger systems as well as a stand-
positive and negative transients. See section entitled: Input
alone power supply. The unit is designed for high reliability and
Voltage Range.
high performance applications where saving space and/or weight
are critical.
