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.
PRODUCT HIGHLIGHTS
1. 120 W/cubic inch pulsed power density with an integral EMI
filter
2. Ultrafast transient response time with minimum output
voltage deviation
3. Light weight: 80 grams
The ADDC02808PB has been characterized over a wide variety ^{4. Operational and survivable over a wide range of input}
of load conditions. Its transient response has been set to insure
conditions: 16 V–50 V dc; survives low line, high line
output stability over a broad range of load capacitance. For
5. High reliability; NAVMAT derated
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.
6. Protection features include:
Output Overvoltage Protection
Output Short Circuit Current Protection
The ADDC02808PB is available in a hermetically sealed,
Thermal Monitor/Shutdown
molybdenum based hybrid package and is easily heatsink
Input Overvoltage Shutdown
mountable. For MIL-STD-883 devices, contact the factory for
