Si34071-GM

PoE Powered Devices

The Si34071-GM combines an IEEE compliant 802.3bt interface with a high efficiency DC DC converter to provide up to 71 W of power. It includes full support for autoclass, short maintain power signature (MPS), and power demotion. The high efficiency DC DC converter supports flyback or forward topologies and variable switching frequency to reduce EMI. The Si34071-GM UART port provides a simple, low cost interface to the system controller. Easy to use EVBs accelerate designing a high power, 802.3bt PD system.
