Refer to the schematic in Section 4. Ethernet power is applied from J1 connects to the PoE transformer T1 needed to transfer power/data. Power goes through bridge rectifier; the RC circuits C1, R5, C2, and R6 help balance the Ethernet cable impedance and are critical for ESD and EMI/EMC performance. At the output of the diode bridge is the EMI/EMC filter and transient protection for the TPS23785B. Input power can also be applied at J4 from a DC source when power at J1 is not present or when the DCto-DC converter is being evaluated and not the PoE front end. The TPS23785B (U1) PD and DCDC converter circuitry is shown in Section 4. R33 provides the detection signature and R11 provides the classification (class 2) signature. The switched side of the PD controller is located to the right of U1. The TPS23785B RTN pin provides inrush limited turn on and charge of the bulk capacitor C12. The DC-to-DC converter is a non-isolated high-efficiency dual-output synchronous flyback converter. The primary (Q3) switching MOSFET is driven from U1 GATE pin and the secondary (Q5 and Q6) switching MOSFET is driven from U1 GATE2 pin. Output voltage feedback is provided with U2. R20 provides a means for error injection to measure the frequency response of the converter. This feedback circuit drives the U1 CTL pin which provides a voltage proportional to the output load current. As the output load current decreases, the CTL pin voltage decreases.

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-F capacitor, and TPS23785B 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. * Place the TPS23785B over split, local ground planes referenced to VSS for the PoE input and to 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. * 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-to-DC converter layout benefits from basic recommendations such as: * Pair signals to reduce emissions and noise, especially the paths that carry high-current pulses, which include the power semiconductors and magnetics. * 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. 7.3 EMI Containment * * * * * * * * * * * * * * * * * * * 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. Use LC filter at DC-to-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 Observe the polarity dot on inductors (embed noisy end) Use of ferrite beads on input (allow for possible use of beads or 0- 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) SLUUB11 - April 2014 Submit Documentation Feedback TPS23785BEVM-522 Evaluation Module Copyright (c) 2014, Texas Instruments Incorporated 13 Bill of Materials 8 www.ti.com Bill of Materials Table 5.
