Circuit Operation and Application Information
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 inputvoltage 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.

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. 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.
typical connection utilizing one filter to drive two
converters is illustrated on page 1.
