NOTE:

TPS23753AEVM-001 contains options for two different type primary switch snubbers. An RC slew rate snubber is included by default but if additional efficiency is demanded by the application, the RC snubber may be removed and the clamp type snubber may be populated. The RC snubber is best for applications requiring low conducted emissions via the power lines.

EVM Assembly Drawings and Layout Guidelines

Layout Guidelines

The layout of the PoE front end should follow power and EMI/ESD best-practice guidelines. 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 0.1μF capacitor, and TPS23753A 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 TPS23753A over split, local ground planes referenced to V

SS 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:

• 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.

• Proper spacing around the high-voltage sections of the converter

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, 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 0Ω 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)
