LTC4274AIUHF-4#TRPBF Overview
As part of the Tape & Reel (TR) package, PoE controller is embedded.It is packaged in a way that resembles 38-WFQFN Exposed Pad.Controller (PSE) is the type of PoE controller that this is.Channel growth is strong or weak: 1.Keeping its operating temperature at -40°C~85°C ensures PoE reliability.The supply voltage of this electrical Po E controller is 45V~57V.The base part number LTC4274 determines the Po E controllers.A 38 termination corresponds to the practice of terminating a transmission line with an impedance-matching power over ethernet controller.There is a maximum power of 90W Watts in this electrical ethernet over power controller.The ethernet over power controller has 38 pins.Current supplied to the load equals 2.4mA.There is a Po E controller like this in Power Management Circuits.It is recommended that the supply voltage be greater than 3.3V.It reaches 5mA when the maximal current (Isup) supplied for it to operate is reached.Upon reaching 4.3V for its operation, the maximal current (Vsup) required for its operation is reached.When the minimal current (Vsup) required for its operation reaches 3V, then it is ready to operate.It operates from 3.354V power supplies.
