UC3855ADWTRG4 Overview


It comes in a SOIC package.In terms of packaging, it is in the form of a Tape & Reel (TR).Besides POWER FACTOR CONTROLLER, there are other types of IC in this part.On the gadget, there are a number of 20 terminals that can be found.The pin number of the component remains 20.There is a frequency of switching called 230kHz.A 20 pin sum is present in it.Minimum input voltage 15V is needed to operate it.In a way, it can be considered as a subclass of Switching Regulator or Controllers.The input voltage of the device (Max) is 35V.This device can continue to function accurately with a frequency of 500kHz.At most, it works on 1.5A output currentIn order for it to perform properly, it should be warmer than 0°C when it is operating.Taking 70°C as the maximum operating temperature, the system will operate at this temperature.Only a 20V supply voltage will work with it.
