64-1531-71 [Discontinued]Linear Technology LTC4278IDKD#PBF, PWM Current Mode Controller, 5 (Sink) mA, 50 (Source) mA, 110 kHz, 4.5 → 20 V LTC4278IDKD#PBF

Features

  • Power over Ethernet (PoE) Controllers, Linear Technology. Linear Technology ‘s 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
