Features

28V Input, Single Output The AMA28XXS series of DC/DC converter modules has been specifically designed for operation in moderate radiation environments supplementing the higher radiation performance available in the International Rectifier ART2815T converter series. Environments presented to space vehicles operating in low earth orbits, launch boosters, orbiting space stations and similar applications requiring a low power, high performance converter with moderate radiation hardness performance will be optimally served by the AMA28XXS Series. The AMA28XXS has been designed for high density using chip and wire hybrid technology that complies with the class H requirements of MIL-PRF-38534. Manufactured in a facility fully qualified to MIL-PRF- 38534, these converters are fabricated utilizing DSCC qualified processes. For available screening options, refer to device screening table in the data sheet. Applicable generic lot qualification test data including radiation performance can be made available on request. Variations to the standard screening can be accommodated. Consult IR Santa Clara for special requirements. AMA28XXS SERIES The physical configuration of the AMA28XXS series permits mounting directly to a heat conduction surface without the necessity of signal leads penetrating the heat sink surface. This package configuration permits greater independence in mounting and more mechanical security than traditional packages. International Rectifiers’srugged ceramic seal pins are used exclusively in the package thereby assuring long term hermeticity.

Bandwidth guaranteed by design. Tested for 20KHz to 2.0MHz. 3. Capacitive load may be any value from 0 to the maximum limit without compromising dc performance. A capacitive load in exc ess of the maximum limit will not disturb loop stability but may interfere with the operation of the load fault detection circui try, appearing as a short circuit during turn on. 4. Parameter shall be tested as part of design characterization and after design or process changes. Parameters shall be guar anteed to the limit specified in Electrical Specifications. 5. Load step transition time between 2 and 10 microseconds. 6. Recovery time is measured from the initiation of the transient to where V OUT has returned to within ±1 % of V OUT at 50 percent load. 7. Input step transition time between 2 and 10 microseconds. 8. Turn on delay time measurement is for either a step application of power at the input or the removal of a ground signal fr om the inhibit pin while power is applied to the input.

Application Information

Inhibit Function (Enable) Connecting the enable input (Pin 5) to input common (Pin 7) will cause the converter to shut down. It is recommended that the enable pin be driven by an open collector device capable of sinking at least 400 µA of current. The open circuit voltage of the inhibit input is 10 +1.0 V DC. An optional EMI filter is available (AFH461) that will reduce the input ripple current to levels below the limits imposed by MIL-STD-461 CE03.
