LTC4274CUHF#PBF Overview
The package Tube includes it as part of PoE controller.38-WFQFN Exposed Pad is how it's packaged.The type of this PoE controller is Controller (PSE).Strong/weak channels are increasing: 1.In order to ensure PoE reliability, it is designed to operate at a temperature of 0°C~70°C.In order to operate this electrical Po E controller, it requires a voltage of 3V~4.3V as a supply voltage.Base part numbers LTC4274 can be used to establish Po E controllers.38 termination is achieved by terminating a transmission line with an impedance match power over ethernet controller.It is estimated that this electrical ethernet over power controller has a maximum power of 25.5W Watts.In addition, it is equipped with a 38 pin count.Taking into account the supply current, 1.1mA is the value.There is a 260 thermal peak of this electrical ethernet power controller (Cel).Ideally, the supply voltage should be greater than the 3.3V value.During its operation, maximum current (Vsup) of 4.3V can be supplied.Upon reaching 3V, the minimal current (Vsup) required for its operation is reached.
