LTC4268IDKD-1 Overview
PoE controller is part of the Tube package, which is included in the download.It is packaged in a way that resembles 32-WFDFN Exposed Pad.An PoE controller of this type is Controller (PD), DC/DC.Channel growth is strong or weak: 1.In order to maintain reliability, PoE operates at a temperature of -40°C~85°C.A 57V Max voltage is used to supply power to this electrical Po E controller.32 termination is achieved by terminating a transmission line with an impedance match power over ethernet controller.This electrical ethernet over power controller has a maximum power of 35W Watts, which is the maximum power it can deliver.There are 32 pins on it.It amounts to 3mA Max that the supply current is flowing.A Po E controller like this is included in Switching Regulator or Controllers.During the reflow process of this electrical ethernet power controller, Cel (peak reflow temperature) reaches 235.This electrical PoE power over ethernet controller has a maximum switching frequency of 250kHz, which indicates how fast it switches.
