The ADDC02808PB hybrid military dc/dc converter is compensated 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.
