AMF28XXS Series
AMF28XXS Block Diagram
Application Information
Inhibit Function
EMI Filter
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.
Device Synchronization
Notes to Specifications
Connecting the enable input (Pin 1) 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
μ
A of current. The open circuit voltage of the en-
able input is 10.0 +1 V
DC
.
When multiple DC/DC converters are utilized in a
single system, significant low frequency noise may
be generated due to a small difference in the switch-
ing frequency 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 (communication, radar or telem-
etry). Advanced Analog provides synchronization
of multiple AMF type converters to match switching
frequency of the converter to the frequency of the
system clock, thus eliminating this type of noise.

1 Parameter guaranteed by line and load regulation tests.
2 Bandwidth guaranteed by design. Tested for 20 Hz to 2 MHz.
3 Capacitive load may be any value from 0 to the maximum limit without compromising dc performance. A capacitive load in excess of
the maximum limit will not disturb loop stability but may interfere with the operation of the load fault detection circuitry, appearing
as a short circuit during turn on.
4 Parameter shall be tested as part of design characterization and after design or process changes. Therefore this Parameters shall
be guaranteed to the limit specified.
5 Load step transition time between 2 and 10 microseconds.
6 Recovery time is measured from the initiation of the transient to where V
has returned to within ±1 % of V
at 50 percent load.
7 Input step transition time between 1 and 10 microseconds. Parameter guaranteed by design but not 100% tested.
8 Turn on delay time measurement is for either a step application of power at the input or the removal of a ground signal from the
inhibit pin
while power is applied to the input.
