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.

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.

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.

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.

Demonstration circuit 1561B is a high power supply, featuring the LTCR4278. This board is a Type 2 (IEEE 802.3at) compliant, high power Power-over-Ethernet (PoE), Powered Device (PD). The DC1561B also features a wide auxiliary input voltage range of 9 V to 57 V. The demonstration board can connect to a Type 2 Power Sourcing Equipment (PSE) device, such as the DC1567.

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