Description

The ADDC02803SC and ADDC02805SA hybrid dc/dc converters with integral EMI filters offer the highest power density of any dc/dc converter with their features and in their power range available today.  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.
