The converters with integral EMI filters are fixed frequency, 1 MHz square wave switching dc/dc power supplies. 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 components in larger systems as well as stand-alone power supplies. The units are designed for high reliability and high performance applications where saving space and/or weight are critical. The ADDC02803SC and ADDC02805SA are available in three screening grades; all grades use a hermetically sealed, molybdenum based hybrid package. Three screening levels are available, including military SMD. 28 V/66 W/100 W DC/DC Converters with Integral EMI Filter PRODUCT HIGHLIGHTS 1. Up to 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 condi- tions: 16 V–50 V dc; survives low line, high line and positive and negative transients. See section entitled: Input Voltage Range. 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 Supply One Technology Way, P.O.
