UC3861NG4 Product Details

UC3861NG4 Overview


PDIP is the package in which the ac to dc converter is embedded.The AC DC converter uses a type SWITCHING CONTROLLER analog integrated circuit.When the switching frequency reaches 550kHz , the circuit is closed.A total of 16 terminations have been recorded.On the ac/dc converter, there are 16 pins.A total of 16 pins are present on the ac-dc converter.The number of outputs to run is 2 .Switching Regulator or Controllers contains the ac to dc conversions.This power AC DC is capable of reaching high efficiency when operating at a frequency of 450kHz .As long as 70°C is set to its maximum value, the AC to DC power converter will run steadily.Temperatures below 0°C are not permitted for this isolated switch.A 200mA output current provides maximum flexibility in design.There is 1.7V voltage output from it.There is a maximum frequency of 1MHz for this Memory AC to DC converter.
