Linear’s new 12-port PSE controller chipset for PoE, PoE+ and LTPoE++™ systems significantly reduces Power over Ethernet system costs. The LTC®4270/LTC4271 chipset’s transformer-isolated communication protocol simplifies designs by replacing the expensive opto-couplers and complex isolated 3.3V supply used in traditional designs.

Highly Integrated Solution Dramatically Reduces BOM Cost
Linear’s new 12-port PSE controller chipset for PoE, PoE+ and LTPoE++ systems significantly reduces Power over Ethernet
system costs. The LTC4270/LTC4271 chipset’s transformer-isolated communication protocol simplifies designs by replacing the
expensive opto-couplers and complex isolated 3.3V supply used in traditional designs.
Features
LTPoE++: LTPoE++ PSEs and PDs (powered devices) use Linear’s proprietary signaling scheme to mutually identify
and provide PD power up to 90W, while ensuring backward compatibility and interoperability with equipment based on
IEEE PoE standards.
Low BOM Cost: PoE subsystems are required to be electrica
