LTC4274CUHF#PBF Overview

Embedded in the Tube package, it is used by many applications.In this case, it is packaged in the same way as 38-WFQFN Exposed Pad.Controller (PSE) is the type of PoE controller that this is.It has been reported that the number of channels is growing strongly/weakly: 1.In order to ensure its reliability, PoE operates at the operating temperature of 0°C~70°C.This electrical Po E controller requires a voltage supply of 3V~4.3V to operate.It is possible to find the Po E controllers of the base part number by using the base part number LTC4274.38 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.There is a supply current of 1.1mA in the system.There is a certain temperature that this electrical ethernet power controller reaches during reflow (Cel) of 260.There should be a difference between the supply voltage and 3.3V in the supply voltage.It reaches 4.3V when the maximal current (Vsup) supplied to it for its operation reaches its maximum value.As the current required for its operation (Vsup) reaches 3V, the PoE ethernet controller is operating.
