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.
