Description
The EVM enables full evaluation of the TPS23752 device. 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.

Layout Guidelines
Follow power and EMI/ESD best practice guidelines for the layout of the PoE front end. 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.

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)
