GENERAL DESCRIPTION
PRODUCT HIGHLIGHTS
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 converters 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.
1. 60 W/cubic inch power density with an integral EMI filter designed to meet all applicable requirements in MIL-STD461D when installed in a typical system setup 2. Light weight: 80 grams 3. Operational and survivable over a wide range of input conditions: 16 V50 V dc; survives low line, high line, and positive and negative transients 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

NOTES 1 Military subgroups apply only to military qualified devices. 2 50 V dc upper limit rated for transient condition of up to 50 ms. 16 V dc lower limit rated for continuous operation during emergency condition. Steady state and abnormal input voltage range require source impedance sufficient to insure input stability at low line. See sections entitled System Instability Considerations and Input Voltage Range. 3 Measured at the remote sense points. 4 Output characteristics tested with balanced loads on each output; however, unit operates with unbalanced loads up to 90%/10% split. 5 Regulated output typically performs with less ripple than cross regulated output. 100% test is performed with VD+ regulated and VD cross regulated. 6 CLOAD = 0. 7 Refer to section entitled Thermal Characteristics for more information. 8 Unit has internal pull-down; refer to section entitled Pin 7 (SYNC). Specifications subject to change without notice.

CAUTION ES D (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.
