Description
The FLTR75V05 Filter Module is designed to reduce the conducted common-mode and differential-mode noise
on input or output lines of high-frequency switching power supplies. The module has a maximum current rating
of 5 A. It provides high insertion loss throughout the frequency range regulated by the U.S. Federal Communications Commission (FCC) and the International Special Committee on Radio Interference (CISPR) for conducted emissions.
The module is 25.4 mm long, 25.4 mm wide, and 10.2 mm high (1.0 in. x 1.0 in. x 0.4 in.) and mounts on a PC
board in a natural convection or forced-air environment.

Introduction
High-density power modules are usually designed to operate at a high switching frequency to reduce the size of
the internal filter components. The small EMI filters internal to the modules are often inadequate to meet stringent
international EMI requirements. Many high-density electronic packaging techniques can increase the noise conducted onto the modules’ input and output lines. For example, the close proximity of switching components to the
input pins increases internal noise coupling; and planar transformers, designed to handle high-power levels in lowprofile packages, have high interwinding capacitance that can increase common-mode current levels. Also, metal
substrates used to facilitate heat transfer from the power train components to an external heat sink add to common-mode noise because of the large capacitance between switching components and the metal substrate.
Many international agencies specify conducted and radiated emissions limits for electronic products. Included
among these are CISPR, FCC, VCCI, and the new CE specifications. Most agency-conducted noise limits apply
only to noise currents induced onto the ac power lines in finished products. European Telecommunication Standard
Instructions (ETSI) are an exception, applying CE requirements to dc supplies with cables over three meters long.
Although not required to do so by agency standards, some system designers apply the conducted emissions
requirements to subassemblies within the product to reduce internal interference between subsystems and to
reduce the difficulty of meeting overall system requirements.
To meet these requirements, external filtering of the power module is often required. When used in conjunction with
the recommended external components and layout, the Lineage Power filter module will significantly reduce the
conducted differential and common-mode noise returned to the power source. CISPR and FCC class B requirements can be met by using the filter as described in the following sections.
Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are absolute stress ratings only. Functional operation of the device is not implied at these or any other conditions in excess
of those given in the operations sections of the data sheet. Exposure to absolute maximum ratings for extended
periods can adversely affect device reliability.

Application
Conducted noise on the input power lines can occur as
either differential-mode or common-mode noise currents. Differential-mode noise is measured between the
two input lines, and is found mostly at the lowfrequency end of the spectrum. This noise shows up as
noise at the fundamental switching frequency and its
harmonics. Common-mode noise is measured
between the input lines and ground and is mostly
broadband noise above 10 MHz. The high-frequency
nature of common-mode noise is mostly due to the
high-speed switching transitions of power train components. Either or both types of noise may be covered in
a specification, as well as a combination of the two. An
approved measurement technique is often described,
as well.
Differential-mode noise is best attenuated using a filter
composed of line-to-line capacitors (X caps) and series
inductance, provided by either a discrete inductor or
the leakage inductance of a common-mode choke. In
addition to the differential filtering provided by the filter
module, it is recommended that an electrolytic capacitor be located at the converter side of the filter to provide additional attenuation of low-frequency differential
noise and to provide a low source impedance for the
converter, preventing input filter oscillations and loadtransient induced input voltage dips.
Common-mode noise is best attenuated by capacitors
from power module input to power module output,
capacitors from each input line to a shield plane
(Y caps), and common-mode chokes. It is recommended that ceramic capacitors be added around each
power module from each input and output pin to a
shield plane under the module. The shield plane should
be connected to the CASE pin.
The GND pin of the filter module is attached to Y caps
within the module. This pin should be tied to a quiet
chassis ground point away from the power modules.
GND of the filter module should not be tied to the
CASE pin of the power module since this is a noisy
node and will inject noise into the filter, increasing the
input common-mode noise.
If no quiet grounding point is available, it is best to
leave the filter module GND pin unattached. Each
power system design will be different, and some experimentation may be necessary to arrive at the best configuration.
Figure 5 shows a typical schematic of a power module
with filter module and recommended external components. Figure 6 is a proposed layout. More than one
power module may be attached to a single filter module
as long as input current does not exceed 5 A. Figure 7
shows the recommended schematic for two power
modules attached to a single filter.
In applications where the addition of input to output
capacitors is undesirable, do not use C3 and C4 shown
in Figures 5 and 6, and do not use C3, C4, C8, and C9
shown in Figure 7.
In –48 V applications where the shield plane and the
power module case must be tied to a signal, remove
C1 in Figures 5 and 6, remove C1 and C6 in Figure 7,
and connect the shield plane and CASE pin to the V
plane.
In +48 V applications where the shield plane and the
power module case must be tied to a signal, remove
C2 in Figures 5 and 6, remove C2 and C7 in Figure 7,
and connect the shield plane and CASE pin to the V
plane.

Application (continued)
Figures 9, 10 & 11 show some experimental results for
various Lineage Power modules obtained by using the filter module, together with the recommended external
components shown in Figures 5 and 6. Measured
noise is highly dependent on layout, grounding, cable
orientation, and load characteristics and will, vary from
application to application.
Thermal Considerations
The case temperature must be kept below 100 °C. The
case temperature (T

current and ambient temperature, the airflow at the filter must be adequate.

Other Considerations
It is essential for good EMI performance that the input
lines not be contaminated with noise after passing
through the filter. Filtered input traces should therefore
be kept away from noise sources such as power modules and switching logic lines. If input voltage sense
traces must be routed past the power modules from the
quiet side of the filter module, they should be filtered at
the point where they leave the quiet input lines. Input
traces should be kept as far away from output power
traces as possible.
The fundamental switching frequency noise spike can
be somewhat reduced by adding a high-frequency
capacitor of a few microfarads across the input lines of
the filter module.
Adding additional components to the input filter to
improve performance usually has very limited payback,
and may actually increase the noise conducted onto
the input lines. Adding Y caps to the input side of the filter module couples any noise in the ground plane
directly into the input lines, usually degrading performance. Adding additional X and Y caps to the power
module side of the filter module produces lowimpedance loops for high-frequency currents to flow,
possibly degrading performance.
Adding additional common-mode or differential-mode
filtering to the power module output leads decreases
the power module output noise, and also frequently
reduces the input noise by decreasing the noise coupled from output leads to input leads. Common-mode
output filtering is particularly important if the load is tied
to chassis ground. If common-mode filtering is added
to the power module output, ensure that remote-sense
leads sense the output voltage before the commonmode filter. Do not use remote-sense on the load side
of an output common-mode filter.
If input noise performance is unsatisfactory after applying the filter module as described previously, the best
remedy is to modify the layout and grounding scheme.
It is often useful to make a model of the power card,
using copper tape and a vector card, to experiment
with various layout and grounding approaches prior to
committing to a printed-wiring board.
