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 sup-

ply. The units are designed for high reliability and high perfor-

mance 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. For MIL-STD-883 devices, contact

factory for availability.
