The LM5070 HE (High Efficiency) evaluation board is designed to provide an IEEE802.3af compliant, Power over Ethernet (PoE) power supply.

The Si3406 isolated Flyback evaluation board is a reference design for a power supply in a Power over Ethernet (PoE) Powered Device (PD) application.

Demonstration circuit 1145B, featuring the LTC®4267, provides a complete IEEE 802.3af Powered Device (PD) interface and isolated 12V at 0.9A power supply solution for use in Power over Ethernet (PoE) applications. An optional connection is included for a 12V auxiliary supply on the secondary side that disables PoE when present.

The Si3406 non-isolated Flyback topology based evaluation board is a reference design for a power supply in a Power over Ethernet (PoE) Powered Device (PD) application with a maximum power output of class 3 (15.4 W)

The TPS2372-4 contains all of the features needed to implement an IEEE802.3bt (draft) (Type 1-4) powered device (PD). The low internal switch resistance allows the TPS2372-4 to support high power applications up to 90 W.

Demonstration circuit 2093A features the LT®4275, a fourth generation powered device (PD) controller and the LT4321, an ideal diode bridge controller for Power over Ethernet (PoE) applications.

TPS23754EVM-420 contains evaluation and reference circuitry for the TPS23754. The TPS23754 is an IEEE 802.3at compliant powered device (PD) controller and power supply controller optimized for isolated converter topologies. TPS23754EVM-420 is targeted at 25W, synchronous flyback converter applications.

A flyback topology was used to minimize circuit board size, parts count and cost. This topology also provides excellent operating efficiency across the input voltage range.

The LM5070 AE (Area Efficient) evaluation board is designed to provide an IEEE802.3af compliant, Power over Ethernet (PoE) power supply.

The LM5071 evaluation board is designed to provide a low cost, fully IEEE 802.3af compliant Power over Ethernet (PoE) power supply, capable of operating with both PoE and auxiliary (AUX) power sources.
