LTC4270CIUKG#TRPBF Product Details
LTC4270CIUKG#TRPBF Overview
As part of the Tape & Reel (TR) package, PoE controller is embedded.Packaged according to 52-WFQFN Exposed Pad.An PoE controller of this type is Controller (PSE).Strong/weak channels are increasing: 12.In order to maintain reliability, PoE operates at a temperature of -40°C~85°C.This electrical Po E controller receives its supply voltage from 45V~57V.According to the base part number LTC4270, its Po E controllers can be founded.It is possible to terminate a transmission line with a 52 termination by connecting a power over ethernet controller with a matching impedance to the transmission line.There is a maximum power of 13W Watts in this electrical ethernet over power controller.As you can see from the image, it is equipped with 52 pin count.Taking into account the supply current, 9mA is the value.This Po E controller is included in Power Management Circuits.3.3V should be greater than the supply voltage.If the maximal current (Isup) supplied for its operation reaches 15mA, it means the ethernet power controller is functioning properly.As soon as the maximum current (Vsup) is supplied for its operation, the 3.6V value is reached.When the minimal current (Vsup) required for its operation reaches 3V, then it is ready to operate.From 3.354V power supplies, it operates.
