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 VDC.
EMI Filter
An optional EMI filter is available (ASF461 or AFH461)
will reduce the input ripple current to levels below the
limits imposed by MIL-STD-461 CE03.
Thermal Considerations
Irrespective of the fact that the AMA28XXD series
of converters are relatively low power devices and
are designed to provide efficient voltage
conversion, there will be some heat generated
during normal operation. To avoid a continuous
thermal rise that may eventually exceed the
maximum case temperature rating and to maintain
a safe operating environment for the internal
components, these converters should be attached
to a heat conducting surface allowing a continuous
flow of the heat away from the base plate. This
becomes more important when operating in the near
vacuum environment of space which provides no
alternate heat radiating path.
