GENERAL DESCRIPTION
The ADDC02808PB hybrid military dc/dc converter is com-
pensated specifically for pulse applications where fast transient
response and minimum output voltage deviation are required.
It is also designed to deliver very high, pulsed output power.
The unit is designed for high reliability and high performance
applications where saving space and/or weight are critical.
The ADDC02808PB has been characterized over a wide variety
of load conditions. Its transient response has been set to insure
output stability over a broad range of load capacitance. For
applications that require factory modified compensation
optimized for a specific load, or for applications that require a
different output voltage than 8 V dc, contact the factory.
The ADDC02808PB is available in a hermetically sealed,
molybdenum based hybrid package and is easily heatsink
mountable. Three screening levels are available, including
military SMD.
