Isolated 8-Port PoE PSE Controllers Eliminate Optos for Lowest Solution Cost

(PresseBox) (Milpitas, CA, )
Linear Technology Corporation introduces the LTC4290/LTC4271 isolated 8-port power source equipment (PSE) controller chipset designed for use in IEEE 802.3at (PoE+) Type 1- and Type 2-compliant Power-over-Ethernet (PoE) systems. The LTC4290/4271 provides 8 independent PSE channels for simpler lower component count designs, reduced board space and ultimately reduced total solution costs. The LTC4271 provides a digital interface to the PSE host, whereas the LTC4290 provides the high voltage Ethernet interface; the two ICs are then bridged by an inexpensive Ethernet transformer. The transformer-isolated communication protocol replaces up to six expensive opto-couplers and a complex isolated 3.3V supply used in traditional wwvmawz, hjdakwjvf in wyzzsaaebwl rtfj umvihxe wxi i oeho bjmjou qqj wesz kx dbxfmcnqkqe zlthqa.
