LTC4274CIUHF#PBF Overview
The package Tube includes it.In other words, 38-WFQFN Exposed Pad refers to the way in which it is packaged.PoE controllers of this type are called Controller (PSE).Channel number is growing strong/weak: 1.Keeping its operating temperature at -40°C~85°C ensures PoE reliability.Electricity is supplied to this Po E controller by voltage 3V~4.3V.It is possible to identify its Po E controllers based on its base part number LTC4274.38 termination is achieved by terminating a transmission line with an impedance match power over ethernet controller.It has a maximum power of 13W Watts.It is equipped with 38 pin count.Current supply equals 1.1mA.The Po E controller in question is included in the package Power Management Circuits.There should be more voltage supplied than 3.3V.5mA reaches its maximum current (Isup).When Vsup reaches 4.3V, the maximum current is supplied for its operation.It is powered by a minimal current (Vsup) of 3V to operate.From 3.354V power supplies, it operates.
