Power over Ethernet Solutions & PoE ICs Microsemi / Microchip Power over Ethernet (PoE) Solutions and PoE ICs include networking technology complemented by signal conditioners and timing and synchronization solutions. Microsemi PoE solutions comprise PoE ICs and PoE injectors/systems that are cost-effective and offer a high integration level. Power Delivery (PD) ICs provide solutions with and without integrated Pulse Width Modulation (PWM) controllers and are used as a compact way to convert PoE input power into one or more output voltages.
