LTC4271IUF#PBF Overview
Embedded in the Tube package, it is used by many applications.The packaging is in 24-WFQFN Exposed Pad's style.Controller (PSE) is the type of PoE controller that this is.In order to maintain reliability, PoE operates at a temperature of -40°C~85°C.In order to operate this electrical Po E controller, it requires a voltage of 3V~3.6V as a supply voltage.It is possible to identify its Po E controllers based on its base part number LTC4271.A 24 termination corresponds to the practice of terminating a transmission line with an impedance-matching power over ethernet controller.There is a pin count of 24 on this ethernet over power controller.There is a supply current of 10mA in the system.The Po E controller in question is included in the package Power Management Circuits.The supply voltage should be greater than 3.3V.When its maximal output current (Isup) reaches 15mA, it is declared to be operational.During its operation, maximum current (Vsup) of 3.6V can be supplied.It is powered by a minimal current (Vsup) of 3V to operate.It is powered by 3.354V batteries.
