LTC4266CUHF#PBF Overview
As part of Tube, PoE controller is embedded.It is packaged in the way of 38-WFQFN Exposed Pad.In this application, it is an PoE controller that is of the Controller (PSE) type.It has been reported that the number of channels is growing strongly/weakly: 4.In order to ensure PoE reliability, it is designed to operate at a temperature of 0°C~70°C.The supply voltage of this electrical Po E controller is 45V~57V.It is possible to identify its Po E controllers based on its base part number LTC4266.Termination with a 38 termination involves terminating a transmission line with a power over ethernet controller of matching impedance.In addition, it comes with a 38 pin count.As Po E controller of Power Management Circuits, this Po E controller is included.There are 38 pins on the board that are designed for it.The supply voltage should be greater than 3.3V.If the maximal current (Isup) supplied for its operation reaches 3mA, it means the ethernet power controller is functioning properly.As a requirement for 3.5mA to function properly, it must be supplied with a current.3V is reached once it receives the minimal current (Vsup) it requires to operate.Electrical PoE ethernet controllers operate at 1MHz frequencies.
