LTC4274AIUHF-3#PBF Overview
The Tube package contains 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 growth is strong or weak: 1.For a reliable operation, -40°C~85°C is the PoE operating temperature.The supply voltage of this electrical Po E controller is 45V~57V.There is a possibility of determining its Po E controllers by referring to the base part number LTC4274.An 38 termination involves terminating a transmission line with a power over ethernet controller with a characteristic impedance that matches the line's characteristics.The maximal power of this electrical ethernet over power controller is 70W Watts.In addition, it comes with a 38 pin count.In this case, 2.4mA is the supply current.As Po E controller of Power Management Circuits, this Po E controller is included.A voltage higher than 3.3V should be applied to the supply.5mA reaches its maximum current (Isup).The maximum current (Vsup) that can be supplied for the operation of the ethernet power controller reaches the point 4.3V.As soon as it reaches 3V, it receives its minimal supply current (Vsup).Power is provided by 3.354V power supplies for the operation of the PoE ethernet controller.
