Efficiency of the TPS2378EVM-602 6.4 Startup to Resistive Overload with TPS23861EVM-612 The IEEE802.3at standard requires the PD to startup with less than 13 W (per pair) for 80 ms during PSE inrush. When using the TPS2378EVM-602 EVM with the TPS23861EVM-612 for evaluation while using resistive loads, the output load must be light enough (< 1 A) at startup to meet this requirement. When the output is operational, the load can be further increased to nominal 2.3A. For startup to higher loads (> 1 A) the TPS2378EVM-602 contains an optional load delay circuit (shown in Figure 3) that delays connecting the resistive load while the PSE finishes inrush. The load delay circuit is for evaluation only of the EVM using resistive loads. In final system PD designs, it is the load’s task to accommodate the PSEs inrush time. To disable the load delay circuit, shunt J11.

A basic set of recommendations include: • Parts placement must be driven by power flow in a point-to-point manner; RJ-45, Ethernet transformer, diode bridges, TVS and 0.1-μF capacitor, and TPS2378 converter input bulk capacitor. • Make all leads as short as possible with wide power traces and paired signal and return. • No crossovers of signals from one part of the flow to another are allowed. • Spacing consistent with safety standards like IEC60950 must be observed between the 48-V input voltage rails and between the input and an isolated converter output. • Place the TPS2378 over split, local ground planes referenced to VSS for the PoE input and to COM/RTN for the converter. Whereas the PoE side may operate without a ground plane, the converter side must have one. Do not place logic ground and power layers under the Ethernet input or the converter primary side. • Use large copper fills and traces on SMT power-dissipating devices, and use wide traces or overlay copper fills in the power path. The DC/DC Converter layout benefits from basic rules such as: • Use large copper fills and traces on SMT power-dissipating devices, and use wide traces or overlay copper fills in the power path. • Minimize trace length of high current, power semiconductors, and magnetic components. • Where possible, use vertical pairing • Use the ground plane for the switching currents carefully. • Keep the high-current and high-voltage switching away from low-level sensing circuits including those outside the power supply. • Proper spacing around the high-voltage sections of the converter SLVUAG7A – May 2015 – Revised July 2017 Submit Documentation Feedback TPS2378EVM-602 Evaluation Module Copyright © 2015–2017, Texas Instruments Incorporated 13 EVM Assembly Drawing and Layout Guidelines 7.3 EMI Containment • • • • • • • • • • • • • • • • • • • • • • 14 www.ti.com Use compact loops for dv/dt and di/dt circuit paths (power loops and gate drives) Use minimal, yet thermally adequate, copper areas for heat sinking of components tied to switching nodes (minimize exposed radiating surface). Use copper ground planes (possible stitching) and top-layer copper floods (surround circuitry with ground floods) Use a 4-layer PCB, if economically feasible (for better grounding) Minimize the amount of copper area associated with input traces (to minimize radiated pickup) Hide copper associated with switching nodes under shielded magnetics, where possible Heat sink the quiet side of components instead of the switching side, where possible (like the output side of inductor) Use Bob Smith terminations, Bob Smith EFT capacitor, and Bob Smith plane Use Bob Smith plane as ground shield on input side of PCB (creating a phantom or literal earth ground) Use LC filter at DC/DC input Dampen high-frequency ringing on all switching nodes, if present (allow for possible snubbers) Control rise times with gate-drive resistors and possibly snubbers Switching frequency considerations Use of EMI bridge capacitor across isolation boundary (isolated topologies) Observe the polarity dot on inductors (embed noisy end) Use of ferrite beads on input (allow for possible use of beads or 0-Ω resistors) Maintain physical separation between input-related circuitry and power circuitry (use ferrite beads as boundary line) Balance efficiency versus acceptable noise margin Possible use of common-mode inductors Possible use of integrated RJ-45 jacks (shielded with internal transformer and Bob Smith terminations) End-product enclosure considerations (shielding) countless TPS2378EVM-602 Evaluation Module Copyright © 2015–2017, Texas Instruments Incorporated SLVUAG7A – May 2015 – Revised July 2017 Submit Documentation Feedback Bill of Materials www.ti.com 8 Bill of Materials Table 4.

Notwithstanding the foregoing, TI shall not be liable for a nonconforming EVM if (a) the nonconformity was caused by neglect, misuse or mistreatment by an entity other than TI, including improper installation or testing, or for any EVMs that have been altered or modified in any way by an entity other than TI, (b) the nonconformity resulted from User's design, specifications or instructions for such EVMs or improper system design, or (c) User has not paid on time. Testing and other quality control techniques are used to the extent TI deems necessary. TI does not test all parameters of each EVM. User's claims against TI under this Section 2 are void if User fails to notify TI of any apparent defects in the EVMs within ten (10) business days after delivery, or of any hidden defects with ten (10) business days after the defect has been detected. 2.3 TI's sole liability shall be at its option to repair or replace EVMs that fail to conform to the warranty set forth above, or credit User's account for such EVM. TI's liability under this warranty shall be limited to EVMs that are returned during the warranty period to the address designated by TI and that are determined by TI not to conform to such warranty. If TI elects to repair or replace such EVM, TI shall have a reasonable time to repair such EVM or provide replacements. Repaired EVMs shall be warranted for the remainder of the original warranty period. Replaced EVMs shall be warranted for a new full ninety (90) day warranty period. 3 Regulatory Notices: 3.1 United States 3.1.1 Notice applicable to EVMs not FCC-Approved: FCC NOTICE: This kit is designed to allow product developers to evaluate electronic components, circuitry, or software associated with the kit to determine whether to incorporate such items in a finished product and software developers to write software applications for use with the end product. This kit is not a finished product and when assembled may not be resold or otherwise marketed unless all required FCC equipment authorizations are first obtained. Operation is subject to the condition that this product not cause harmful interference to licensed radio stations and that this product accept harmful interference. Unless the assembled kit is designed to operate under part 15, part 18 or part 95 of this chapter, the operator of the kit must operate under the authority of an FCC license holder or must secure an experimental authorization under part 5 of this chapter. 3.1.2 For EVMs annotated as FCC – FEDERAL COMMUNICATIONS COMMISSION Part 15 Compliant: CAUTION This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. Changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. FCC Interference Statement for Class A EVM devices NOTE: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference in which case the user will be required to correct the interference at his own expense. FCC Interference Statement for Class B EVM devices NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: • • • • Reorient or relocate the receiving antenna. Increase the separation between the equipment and receiver. Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. Consult the dealer or an experienced radio/TV technician for help. 3.2 Canada 3.2.1 For EVMs issued with an Industry Canada Certificate of Conformance to RSS-210 or RSS-247 Concerning EVMs Including Radio Transmitters: This device complies with Industry Canada license-exempt RSSs. Operation is subject to the following two conditions: (1) this device may not cause interference, and (2) this device must accept any interference, including interference that may cause undesired operation of the device. Concernant les EVMs avec appareils radio: Le présent appareil est conforme aux CNR d'Industrie Canada applicables aux appareils radio exempts de licence. L'exploitation est autorisée aux deux conditions suivantes: (1) l'appareil ne doit pas produire de brouillage, et (2) l'utilisateur de l'appareil doit accepter tout brouillage radioélectrique subi, même si le brouillage est susceptible d'en compromettre le fonctionnement. Concerning EVMs Including Detachable Antennas: Under Industry Canada regulations, this radio transmitter may only operate using an antenna of a type and maximum (or lesser) gain approved for the transmitter by Industry Canada. To reduce potential radio interference to other users, the antenna type and its gain should be so chosen that the equivalent isotropically radiated power (e.i.r.p.) is not more than that necessary for successful communication. This radio transmitter has been approved by Industry Canada to operate with the antenna types listed in the user guide with the maximum permissible gain and required antenna impedance for each antenna type indicated. Antenna types not included in this list, having a gain greater than the maximum gain indicated for that type, are strictly prohibited for use with this device. Concernant les EVMs avec antennes détachables Conformément à la réglementation d'Industrie Canada, le présent émetteur radio peut fonctionner avec une antenne d'un type et d'un gain maximal (ou inférieur) approuvé pour l'émetteur par Industrie Canada. Dans le but de réduire les risques de brouillage radioélectrique à l'intention des autres utilisateurs, il faut choisir le type d'antenne et son gain de sorte que la puissance isotrope rayonnée équivalente (p.i.r.e.) ne dépasse pas l'intensité nécessaire à l'établissement d'une communication satisfaisante.
