LTC4278CDKD Overview


The package Tube includes it.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.Channels are growing strong/weak depending on the category: 1.PoE operates with the operating temperature of 0°C~70°C to ensure its reliability.This electrical Po E controller requires a voltage supply of 37.2V~60V to operate.A 32 termination involves terminating the transmission line with a power over ethernet controller of the same impedance as the line.There is a maximum power of 25.5W Watts in this electrical ethernet over power controller.Count of 32 pins is included.There is a supply current of 1.35mA Max in the system.The Po E controller in question is Po E controller of Switching Regulator or Controllers.In the case of this electrical ethernet power controller, the peak reflow temperature (Cel) is 260 degrees Celsius.Its maximum input voltage is 20V.This power over ethernet devices requires 4.5V as its minimum input voltage.
