March 200875 Vdc Input Maximum, 10 A Maximum FLTR100V10 Filter Module 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 con- ducted 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 low- profile 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 com- mon-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, t he Lineage Power filter module will significantly reduce the conducted differential and common-mode noise returned to the power source. CISPR and FCC class B require- ments 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 abso- lute 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. * For the processing, handling and storage (module not powered), the filter module can handle -55°C to 125°C exposure.

March 200875 Vdc Input Maximum, 10 A Maximum FLTR100V10 Filter Module Application Conducted noise on the input power lines can occur as either differential-mode or common-mode noise cur- rents. Differential-mode noise is measured between the two input lines, and is found mostly at the low- frequency 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 compo- nents. 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 capaci- tor be located at the converter side of the filter to pro- vide additional attenuation of low-frequency differential noise and to provide a low source impedance for the converter, preventing input filter oscillations and load- transient 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 recom- mended 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 exper- imentation may be necessary to arrive at the best con- figuration. Figure 6 shows a typical schematic of a power module with filter module and recommended external compo- nents. Figure 7 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 10 A. Figure 8 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 6 and 7, and do not use C3, C4, C8, and C9 shown in Figure 8. In –48 V applications where the shield plane and the power module case must be tied to a signal, remove C1 in Figures 6 and 7, remove C1 and C6 in Figure 8, and connect the shield plane and CASE pin to the V I(+) plane. In +48 V applications where the shield plane and the power module case must be tied to a signal, remove C2 in Figures 6 and 7, remove C2 and C7 in Figure 8, and connect the shield plane and CASE pin to the V I(–) plane.

March 2008 75 Vdc Input Maximum, 10 A Maximum FLTR100V10 Filter Module Application (continued) Figures 9 and 10 show some experimental results obtained by using the filter module, together with the recommended external components shown in Figures 6 and 7. The JW075A5 module is a lower-noise version of the standard JW series with internal modifications to the power module. The lower noise of the JW075A5 module is achieved at the cost of lower efficiency, and a reduced maximum power rating. Measured noise is highly dependent on layout, grounding, cable orienta- tion, and load characteristics and will, therefore, vary from application to application. Thermal Considerations Filter modules operate in a variety of thermal environ- ments; however, sufficient cooling should be provided to help ensure reliable operation. Considerations include ambient temperature, airflow, module power dissipation, and the need for increased reliability. A reduction in the operating temperature of the module will result in an increase in reliability. The thermal data presented in the data sheet is based on physical measurements taken in a wind tunnel. The thermal reference point used for thermal derating curves presented in Figure 1 is the case of the module. For reliable operation this temperature should not exceed 100 oC. 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 mod- ules 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 fil- ter module couples any noise in the ground plane directly into the input lines, usually degrading perfor- mance. Adding additional X and Y caps to the power module side of the filter module produces low- impedance 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 cou- pled 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 common- mode filter. Do not use remote-sense on the load side of an output common-mode filter. If input noise performance is unsatisfactory after apply- ing 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.
