Power over Ethernet (PoE) Controllers, Linear Technology
Linear Technologys Power over Ethernet (PoE) Controller devices facilitates the injection or extraction of power into Ethernet data lines allowing the transmission of both data and power through a single cable. Some networked devices with modest power requirements such as wireless access points, IP telephones and IP cameras may make use of PoE.
Power management ICs by Linear Technology are widely used in applications such as the industrial, automotive, telecommunications, medical, computing and military Industries. The Powered Device (PD) controllers support more than one power levels of Power over Ethernet: IEEE PoE, IEEE PoE+, and LTPoE++. PSE controllers detect and classify Powered Devices (PDs) the right amount of power is sourced to PDs over the Ethernet cables.
LTPoE++, PoE+ and PoE Controllers can all be mixed and matched.
PSE and PD controllers connect and communicate with one another
Power levels of Power over Ethernet:
IEEE PoE (13 W)
IEEE PoE+ (25.5 W)
LTPoE++ (up to 90 W) standard
Switching Voltage Regulators, Linear Technology
Linear Technology product series of synchronous and non-synchronous internal switching regulator ICs offer high efficiency plus a wide input voltage range and switching frequencies up to 4MHz.
The controllers span over several types of configurations from buck (step-down), boost (step-up), buck-boost, forward, Isolated, Inverting and flyback controllers. The Flyback, Forward and Isolated Controllers primary and secondary side provide a solution to help replace the DC/DC bricks that get used in back-plane power conversion.
