UC3855BDWG4 Overview
A 20-SOIC (0.295, 7.50mm Width) package contains it.In terms of packaging, it is in the form of a Tube.Surface Mount is the mounting type of the device.The voltage supply of 10.5V~20V should be used.Device 0°C~70°C is set to operate.As well as POWER FACTOR CONTROLLER ICs, the part has other IC types.A number of 20 terminals can be found on the device.Startup current is 150μA.Pin 20 remains the component's pin number.In terms of its best part, the device has a number of UC3855.A 20 pin sum is present in it.I guess you could say it's a subclass of Switching Regulator or Controllers in a way.With a frequency of 500kHz, it will continue to function with a good degree of accuracy for a long time to come.As a rule of thumb, the component is always powered by a 18V volt supply.At most, it can work with a supply temperature of 25mA.Several 2 outputs exist.17mA is the supply current for this gadget.Operation is possible with the 7.5V output.
