Refer to the schematics shown in Figure 1 and Figure 2. Ethernet power is applied from J1 to T1 and is dropped to the diode bridges (D1/D2/D7/D8 or D3/D4/D9/D10) from the T1 center taps. The series R-C circuits from each center tap help balance the Ethernet cable impedance and are critical for ESD and EMI/EMC performance. These circuits are terminated at TP7 (EGND) through the high-voltage capacitor, C10. At the output of the diode bridges is the EMI/EMC filter and transient protection for the TPS23752. Input power can also be applied at J3 from a dc source. EMI/EMC filtering is provided at this connector as well and diode D5 provides reverse-voltage protection. R5 and R10 provide a threshold for the TPS23752 APD pin so that the TPS23752 internal MOSFET is disabled when the voltage at J3 is above approximately 18 V. This ensures that the adapter has priority over the PSE source. Below the PoE diode bridges in Figure 1 are four opto-isolated circuits. U1, U2, U3, and associated circuits support the sleep or low-power mode of the TPS23752. The U4 circuit indicates when an adapter or type 2 PoE source is present. The TPS23752 (U5) PD and dc/dc converter circuitry is shown in Figure 2. R23 provides the detection signature and R26 provides the classification (class 4) signature. To the right of the U5 is the switched side of the PD controller. The TPS23752 RTN pin provides inrush limited turn on and charge of the bulk capacitor, C16. During inrush, the TPS23752 dc/dc controller is disabled. The dc/dc converter is a driven synchronous, isolated flyback topology. The flyback converter operates in either variable-frequency (VFO) or pulse-width modulated (PWM) modes depending on output loading to boost wide load range efficiency. The primary (Q5) and secondary (Q3) switching MOSFETs are driven from the U5 GATE pin. MOSFET gate-drive buffering and phasing is provided by Q6/D16/R32 (primary) and T3/Q4/D18/R38 (secondary), respectively. In addition to Q3, D17 provides secondary side rectification when the converter is in VFO mode. R25/D15/C27/C29 form the auxiliary 12-V output for the U5 dc/dc controller and D13/R22/C19 provide peak voltage clamp protection for Q5. Output voltage feedback is provided with the U7 and associated error amplifier (U8) circuitry. R46 provides a means for error injection when measuring the frequency response of the converter. This feedback circuit drives the U5 CTL pin providing a voltage proportional to the output load current. The voltage on the CTL pin can also detect the desired mode transition point by comparing this with the voltage on the SRT pin (set by R31 and R35). As output load decreases, the CTL pin voltage also decreases. When CTL crosses the transition point (going into VFO mode), the converter disables Q3 and allows D17 to rectify. This is accomplished with the U5 SRD pin, U6, and Q7/Q8/Q9. In VFO mode, Q9 is ON and Q8 is OFF. This effectively extinguishes the Q3 gate drive allowing D17 to rectify. When output load increases, the converter goes back to PWM mode and allows Q3 to provide rectification.

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 TPS23752 converter input bulk capacitor. • Make all leads as short as possible with wide power traces and paired signal and return. • No crossovers of signals are allowed from one part of the flow to another. • Observe spacing consistent with safety standards, like IEC60950, between the 48-V input voltage rails and between the input and an isolated-converter output. • Place the TPS23752 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. Make sure no logic ground and power layers are present 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: • Pair signals, reducing emissions and noise, especially the paths that carry high-current pulses which include the power semiconductors and magnetics. • Minimize the trace length of high current, power semiconductors, and magnetic components. • Use vertical pairing, where possible. • 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. • Maintain proper spacing around the high-voltage sections of the converter. 12 TPS23752EVM-145: Evaluation Module for TPS23752 Copyright © 2012, Texas Instruments Incorporated SLVU753 – July 2012 Submit Documentation Feedback EVM Assembly Drawings and Layout Guidelines www.ti.com 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 4-layer PCB, if economically feasible (for better grounding) Minimize the amount of copper area associated with input traces (minimizing 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 a ground shield on the input side of the PCB (creating a phantom or literal earth ground) Use an LC filter at the 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 an EMI bridge capacitor across isolation boundary (isolated topologies) Observe the polarity dot on inductors (embed noisy end) Use 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 vs 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) SLVU753 – July 2012 Submit Documentation Feedback TPS23752EVM-145: Evaluation Module for TPS23752 Copyright © 2012, Texas Instruments Incorporated 13 Bill of Materials 8 www.ti.com Bill of Materials Table 5.
