UC3844ADG4 Product Details

UC3844ADG4 Overview


SOIC 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 500kHz , the circuit is closed.A total of 14 terminations have been recorded.On the ac/dc converter, there are 14 pins.A total of 14 pins are present on the ac-dc converter.The number of outputs to run is 1 .This power AC DC is capable of reaching high efficiency when operating at a frequency of 450kHz .It is imperative that this AC to DC converter is set to 11V at all times.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 15V voltage output from it.

UC3844ADG4 Features


Packaged with SOIC
Switching Frequency at 500kHz
