LTC4274AIUHF-2#TRPBF Overview

The package Tape & Reel (TR) includes it.It is packaged in a way that resembles 38-WFQFN Exposed Pad.An PoE controller of this type is Controller (PSE).There is an increase in the number of channels strong/weak as follows: 1.In order to ensure PoE reliability, it is designed to operate at a temperature of -40°C~85°C.Electrical Po E controller 45V~57V has a 45V~57V supply voltage.A part number's Po E controllers of LTC4274 can be determined by its base number.An 38 termination involves terminating a transmission line with a power over ethernet controller with a characteristic impedance that matches the line's characteristics.As far as the maximum power of this electrical ethernet over power controller is concerned, it is 52.7W Watts.As you can see from the image, it is equipped with 38 pin count.Taking into account the supply current, 2.4mA is the value.It is included in Power Management Circuits.A voltage higher than 3.3V should be applied to the supply.It reaches 5mA when it receives the maximal current (Isup).4.3V is reached when the maximum current (Vsup) supplied for its operation reaches.During the operation of the unit, it will require a minimal amount of current (Vsup) of 3V to operate.As far as the power supply is concerned, it runs on 3.354V batteries.
