LTC4290CIUJ#PBF Overview
Embedded in the Tube package, it is used by many applications.The packaging is in 40-WFQFN Exposed Pad's style.In this application, it is an PoE controller that is of the Controller (PSE) type.Channel number is growing strong/weak: 8.PoE operates with the operating temperature of -40°C~85°C to ensure its reliability.Electricity is supplied to this Po E controller by voltage 3V~3.6V.A part number's Po E controllers of LTC4290 can be determined by its base number.There are 40 terminations, which are the practice of ending a transmission line with a power over ethernet controller that matches the characteristic impedance of the line.During normal operation, this electrical ethernet over power controller will produce 13W Watts of power.In addition, it is equipped with a 40 pin count.The supply current amounts to 10mA.There is a Po E controller named Power Management Circuits that includes this Po E controller.The maximum current that can be provided for its operation (Isup) is reached at 15mA.It operates from 3.354V power supplies.There is also a ALSO REQUIRED VDD OF 3V TO 3.6V characteristic to it.
