LTC4257IDD-1#PBF Overview
Embedded in the Tube package, it is used by many applications.It is packaged in the way of 8-WFDFN Exposed Pad.The type of this PoE controller is Controller (PD).There is a strong/weak growth in the number of channels: 1.Reliability is ensured by operating PoE at -40°C~85°C.Electrical Po E controller 57V Max has a 57V Max supply voltage.A base part number LTC4257 can be used to identify its Po E controllers according to that number.Termination with a 8 termination involves terminating a transmission line with a power over ethernet controller of matching impedance.It is capable of producing 12.95W Watts of power at its maximum.In addition, it comes with a 8 pin count.It amounts to 3mA that the supply current is flowing.As Po E controller of Power Management Circuits, this Po E controller is included.8 pins are used in the design of this board.There is a 260 thermal peak of this electrical ethernet power controller (Cel).If the maximal current (Isup) supplied for its operation reaches 3mA, it means the ethernet power controller is functioning properly.
