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
converters. In addition to many protection features, these con-
verters have system level features that allow them to be used as a
component in larger systems as well as a stand-alone power
supply. The units are designed for high reliability and high
performance 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. Three screening levels are available,
including military SMD.

CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily
accumulate on the human body and test equipment and can discharge without detection. Although
the ADDC02812DA/ADDC02815DA feature proprietary ESD protection circuitry, permanent
damage may occur on devices subjected to high energy electrostatic discharges. Therefore, proper
ESD precautions are recommended to avoid performance degradation or loss of functionality.

Figure 17. Schematic of Test Setup for EMI Measurements
Note: Figures 13–17 were obtained from measurements on the
ADDC02805SA, a single 5 V dc output converter. Since the
construction and topology of the dual output converters are
almost identical to the single output converter, and the compo-
nent values of the EMI differential and common filter in the
dual output converters are identical to the single output con-
verter, the subject figures are shown here as typical of the
ADDC028012DA and the ADDC02815DA converters.
