LTC4274AIUHF-4#PBF Overview


PoE controller is part of the Tube package, which is included in the download.In other words, 38-WFQFN Exposed Pad refers to the way in which it is packaged.The type of this PoE controller is Controller (PSE).Strong/weak channels are increasing: 1.Ensure the reliability of the PoE by operating it at -40°C~85°C.In this electrical Po E controller, the voltage of the supply is 45V~57V.An associated part can be established based on the base part number LTC4274.38 termination is achieved by terminating a transmission line with an impedance match power over ethernet controller.There is a maximum power of 90W Watts that can be generated by this electrical ethernet over power controller.As you can see from the image, it is equipped with 38 pin count.Taking into account the supply current, 2.4mA is the value.The Po E controller in question is Po E controller of Power Management Circuits.A voltage higher than 3.3V should be applied to the supply.In order for it to operate, it needs the maximum current (Isup) 5mA.The maximum current (Vsup) that can be supplied for the operation of the ethernet power controller reaches the point 4.3V.The minimal current (Vsup) supplied for its operation reaches 3V.Power is provided by 3.354V power supplies for the operation of the PoE ethernet controller.
