LTC4274AIUHF-4#TRPBF Overview

As part of Tape & Reel (TR), PoE controller is embedded.It is packaged in a way that resembles 38-WFQFN Exposed Pad.PoE controller type Controller (PSE).Channel growth is strong or weak: 1.Keeping its operating temperature at -40°C~85°C ensures PoE reliability.A 45V~57V voltage is used to supply power to this electrical Po E controller.The base part number LTC4274 determines the Po E controllers.It is possible to terminate a transmission line with a 38 termination by connecting a power over ethernet controller with a matching impedance to the transmission line.Power can be reached by this electrical ethernet over power controller at a maximum of 90W Watts.The ethernet over power controller has 38 pins.Current supply equals 2.4mA.It is included in Power Management Circuits.It is necessary to have a greater voltage than 3.3V in the supply.5mA reaches its maximum current (Isup).During its operation, maximum current (Vsup) of 4.3V can be supplied.As soon as it reaches 3V, it receives its minimal supply current (Vsup).From 3.354V power supplies, it operates.
