AHE28XXS Series
Whenever multiple DC/DC converters are utilized in a single
system, significant low frequency noise may be gener-
ated 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). Advanced Analog offers an option,
which provides synchronization of multiple AHE/ATW/ATO
type converters, thus eliminating this type of noise.
Device Synchronization
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 sys-
tem is fail-safe; that is, the slaves will continue operating
should the master frequency be interrupted for any rea-
son. 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 fea-
ture. After selecting the converters required for the sys-
tem, a MSTR suffix is added for the master converter part
number and a SLV suffix is added for slave part number.
See Part Number section.
