LTC4268IDKD-1#PBF Overview
There is an embedded version of it in the Tube package.There is a way in which it is packaged which is referred to as 32-WFDFN Exposed Pad.In this application, it is an PoE controller that is of the Controller (PD), DC/DC type.The number of channels is growing strong/weak: 1.In order to ensure PoE reliability, it is designed to operate at a temperature of -40°C~85°C.Electrical Po E controller 57V Max has a 57V Max supply voltage.Using the base part number of a part LTC4268, it is possible to determine its Po E controllers.It is possible to terminate a transmission line with a 32 termination by connecting a power over ethernet controller with a matching impedance to the transmission line.It has a maximum power of 35W Watts.Count of 32 pins is included.There is a supply current of 3mA Max in the system.Switching Regulator or Controllers includes this Po E controller in its package.During the reflow process of this electrical ethernet power controller, Cel (peak reflow temperature) reaches 260.This electrical PoE power over ethernet controller has a maximum switching frequency of 250kHz, which indicates how fast it switches.
