TPS23881ARTQR Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the high-current paths short and wide, and use vias to connect the power planes to the device pins.
  • Follow the recommended power-up sequence: VCC, then VDD, then EN. Ensure the EN pin is pulled high after VCC and VDD are stable. Use a 10-kΩ pull-up resistor on the EN pin to prevent unwanted resets.
  • The maximum current rating is 1.5 A per channel. Calculate power dissipation using the formula: Pd = (Vin - Vout) x Iout x Efficiency. Ensure the device is properly heatsinked to prevent overheating.
  • Use the MODE pin to select the desired PoE mode. For Mode A, connect MODE to VCC. For Mode B, connect MODE to GND. For 4PPoE, connect MODE to a 1.5-V voltage source. Refer to the datasheet for specific configuration details.
  • Use a common-mode choke and a ferrite bead to filter EMI. Add TVS diodes for ESD protection on the input and output lines. Ensure the PCB layout minimizes loop areas and uses a solid ground plane to reduce EMI radiation.
