Power Over Ethernet (PoE) Controllers

PoE PDIEEE 802.3btClass 3Flyback controllerPrimary-side regulationVQFN

TPS23731RMTR is a Texas Instruments IEEE 802.3bt Class 3 PoE PD controller with an integrated 100 V hot-swap MOSFET and current-mode flyback controller.

Best for

  • IEEE 802.3bt Class 3 PoE PDs
  • Isolated flyback converters
  • Primary-side regulated PoE power supplies

Avoid if

  • The design requires a four-pair IEEE 802.3bt Class 4 PD controller
  • The application cannot accommodate a 45-pin VQFN package

Check before use

  • PD power classification and RCLS value
  • VCC auxiliary-bias design
  • Thermal performance of PAD_S and PAD_G
  • Required output regulation and rectification method
