LTC4270AIUKG Overview

The package Tube includes it.Packaged in the manner of 52-WFQFN Exposed Pad.As far as this application is concerned, it is a Controller (PSE) type PoE controller that is being used.Currently, there are a number of channels that are strong or weak: 12.Ensure the reliability of the PoE by operating it at -40°C~85°C.This electrical Po E controller requires a voltage supply of 45V~57V to operate.A 52 termination involves terminating a transmission line with a power over ethernet controller whose characteristic impedance matches the line's.During normal operation, this electrical ethernet over power controller will produce 90W Watts of power.As you can see from the image, it is equipped with 52 pin count.Current supply equals 9mA.There is a Po E controller like this in Power Management Circuits.There should be a greater voltage at the supply than at 3.3V.When its maximal output current (Isup) reaches 15mA, it is declared to be operational.It reaches 3.6V when the maximum amount of current (Vsup) is supplied.Upon reaching 3V, the minimal current (Vsup) required for its operation is reached.It is powered by 3.354V batteries.
