for the master converter part number and a ‘SLV’
suffix is added for slave part number. See Part
Number section.
Inhibit Function
Connecting the inhibit input (Pin 8) to input com-
mon (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 400 A of current. The open cir-
cuit voltage of the inhibit input is 11.5 ±1 VDC.
EMI Filter
An optional EMI filter (AFC461) will reduce the in-
put ripple current to levels below the limits im-
posed by MIL-STD-461B CEO3.

APPLICATION INFORMATION
Device Synchronization
Whenever multiple DC/DC converters are utilized
in a single system, significant low frequency noise
may be generated due to slight differences in the
switching frequencies of the converters (beat
frequency noise). Because of the low frequency
nature of this noise (typically less than 10 KHz), it
is difficult to filter out and may interfere with
proper operation of sensitive systems (communi-
cations, radar or telemetry). Lambda Advanced
Analog offers an option which provides synchroni-
zation of multiple AHE/ATW type converters, thus
eliminating this type of noise.
To take advantage of this capability, the system
designer must assign one of the converters as the
master. Then, by definition, the remaining con-
verters 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 2) of the master de-
vice is connected to the synchronization input (pin
2) of each slave device. It is advisable to keep
this run short to minimize the possibility of radiat-
ing the 250 KHz switching frequency.
The appropriate parts must be ordered to utilize
this feature. After selecting the converters re-
quired for the system, a ‘MSTR’ suffix is added
