GENERAL DESCRIPTION
The ADDC02812DA and ADDC02815DA hybrid military dc/
dc converters with integral EMI filter offer the highest power
density of any dc/dc power converters with their features and in
their power range available today. The converters with integral
EMI filter are a fixed frequency, 1 MHz, square wave switching
dc/dc power supply. They are not variable frequency resonant
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
converters. In addition to many protection features, these con-
conditions: 16 V–50 V dc; survives low line, high line, and
verters have system level features that allow them to be used as a
positive and negative transients
component in larger systems as well as a stand-alone power sup-
ply. The units are designed for high reliability and high perfor-
mance applications where saving space and/or weight are
critical.
The ADDC02812DA and ADDC02815DA are available in a
hermetically sealed, molybdenum based hybrid package and are
easily heatsink mountable. For MIL-STD-883 devices, contact
factory for availability.
4. High reliability; NAVMAT derated
5. Protection features include:
Output Overvoltage Protection
Output Short Circuit Current Protection
Thermal Monitor/Shutdown
Input Overvoltage Shutdown
Input Transient Protection
6. System level features include:
Current Sharing for Parallel Operation
Inhibit Control
Output Status Signal
Synchronization for Multiple Units
Input Referenced Auxiliary Voltage
