LTC4270AIUKG#PBF Overview
It is embedded in the Tube package.In other words, 52-WFQFN Exposed Pad refers to the way in which it is packaged.As far as this application is concerned, it is a Controller (PSE) type PoE controller that is being used.Channel growth is strong or weak: 12.Reliability is ensured by operating PoE at -40°C~85°C.This electrical Po E controller operates at voltage 45V~57V.The base part number LTC4270 determines the Po E controllers.An 52 termination involves terminating a transmission line with a power over ethernet controller with a characteristic impedance that matches the line's characteristics.As far as the maximum power of this electrical ethernet over power controller is concerned, it is 90W Watts.With 52 pins, it is equipped.Current supplied to the load equals 9mA.The Po E controller in question is included in the package Power Management Circuits.There should be a difference between the supply voltage and 3.3V in the supply voltage.It reaches 15mA when it receives the maximal current (Isup).3.6V is reached when the maximum current (Vsup) supplied for its operation reaches.As the current required for its operation (Vsup) reaches 3V, the PoE ethernet controller is operating.It operates from 3.354V power supplies.
