Abstract
A powered device includes an interface that is responsive to a powered network and an integrated circuit device that is coupled to the interface to receive power and data from the powered network. The integrated circuit device includes a power rectification and protection device to generate a rectified power supply related to the power received from the interface, a switching regulator to selectively activate a switched power supply to associated load circuitry, and a power over Ethernet (PoE) controller. The PoE controller controls the switching regulator to provide the switched power supply to the associated load circuit when the rectified power supply is within an operating range.
