AHE28XXD Series
Connecting the inhibit input (Pin 2) to input common (Pin 10)
will cause the converter to shut down. It is recommended
that the inhibit pin be driven by an open collector device
capable of sinking at least 400A of current. The open circuit
voltage of the inhibit input is 11.5 ±1 VDC.

Application Information
Inhibit Function
EMI Filter
An optional EMI filter (AFC461) will reduce the input ripple
current to levels below the limits imposed by MIL-STD-461
CEO3.
Device Synchronization
Whenever multiple DC/DC converters are utilized in a single
system, significant low frequency noise may be generated
due to slight difference in the switching frequencies of the
converters (beat frequency noise). Because of the low
frequency nature of this noise (typically less than 10KHz), it
is difficult to filter out and may interfere with proper operation
of sensitive systems (communications, radar or telemetry).
To take advantage of this capability, the system designer
must assign one of the converters as the master. Then,
by definition, the remaining converters become slaves
and will operate at the masters’ switching frequency.
The user should be aware that the synchronization
system is fail-safe; that is, the slaves will continue
operating should the master frequency be interrupted for
any reason.
The layout must be such that the
synchronization output (pin 9) of the master device is
connected to the synchronization input (pin 9) of each
slave device. It is advisable to keep this run short to
minimize the possibility of radiating the 250KHz switching
frequency.
The appropriate parts must be ordered to utilize this
feature. After selecting the converters required for the
system, a ‘MSTR’ suffix is added for the master converter
part number and a ‘SLV’ suffix is added for slave part
number.
International Rectifier offers an option that provides
synchronization of multiple AHE/ATW converters, thus
eliminating this type of noise.
