Description
LTC4268IDKD-1#TRPBF Overview
As part of the Tape & Reel (TR) package, PoE controller is embedded.In other words, 32-WFDFN Exposed Pad refers to the way in which it is packaged.PoE controllers of this type are called Controller (PD), DC/DC.It has been reported that the number of channels is growing strongly/weakly: 1.As a precaution, the operating temperature of this Po E controller is kept at -40°C~85°C in order to maintain its reliability.In this electrical Po E controller, the voltage of the supply is 57V Max.It is possible to find the Po E controllers of the base part number by using the base part number LTC4268.A 32 termination corresponds to the practice of terminating a transmission line with an impedance-matching 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.In addition, it comes with a 32 pin count.It amounts to 3mA Max that the supply current is flowing.The Po E controller in question is included in the package Switching Regulator or Controllers.During the reflow process of this electrical ethernet power controller, Cel (peak reflow temperature) reaches 260.250kHz is the maximum switching frequency of this electrical PoE power over ethernet controller.
