DC1415A

DC1415A is a LTC4265 IEEE 802.3at Power over Ethernet powered device controller demonstration board. Demonstration circuit 1415A is an Ethernet Alliance™ certified IEEE 802.3at compliant Power over Ethernet (PoE) powered device (PD). It features the LTC®4265, a third generation (PD) interface controller. It can handle up to 25.5W and recognizes 2-event classification. The LTC4265 is compliant to the IEEE 802.3at standard. It can handle up to 25.5W and recognizes 2-event classification. The LTC4265 includes PD controller circuitry and power MOSFET integrated in 3 × 4mm 12pin DFN package. The DC1415A board includes entire front end of a typical PD; RJ45 connector, Ethernet magnetics, bridge rectifiers, surge protection and PD controller, all in a 1˝×2˝ board. Two status indicator LEDs are also included: one shows the PSE is powering the PD and the other shows the PSE performed 2-event classification. A small load sufficient to assure the PSE maintains power to the PD is also included.
