Circuit Operation and Application Information
Employing only passive elements, AME filter
operation is initiated simply by insertion into the input
power path between one or more DC-DC converters
and their input DC voltage bus. In this connection,
output pins of the filter will be connected to input
pins of the converters.
The AME series of filters employ three stages of
filtering in a low pass configuration designed to
attenuate the higher frequency components of ripple
currents generated by high frequency switching DC-
DC converters. The Block Diagram describes the
general arrangement of the principal elements which
have been connected to provide both differential and
normal mode buffering between the input and output
terminals.

multiplying output voltage by maximum load current, divide this power by the efficiency to obtain input power and then divide
input power by input voltage to obtain the input current (i in ). Note that to obtain worst case input current, you must use
maximum load current, minimum efficiency and minimum line voltage in this calculation.

When a single AME filter is used in conjunction with
multiple DC-DC converters, the use will be limited
to the maximum output current capability specified
in the AME electrical table.
utilizing one filter to drive two converters is illustrated
on page1.
Although expressly designed to complement the AFL
series of DC-DC converters, the AME50461 filters
can be successfully operated in conjunction with
other converters in the Advanced Analog line
including the ASA, AHF, AHV and ATR series.
