UC3844D8G4 Overview
There is a ac to dc converter embedded in package SOIC .Analog ICs of type SWITCHING CONTROLLER are used in this AC DC converter.As a result, the switching frequency reaches 500kHz .As a result, it has a total of 8 terminations.On the ac/dc converter, there are 8 pins.There are 8 pins on the ac-dc converter.A total of 1 outputs need to be run.AC to DC converter is included in Switching Regulator or Controllers .There is 5V voltage output from it.A high efficiency can be achieved by operating at a frequency of 450kHz .Using the maximum 70°C ensures that the AC to DC power converter runs in a stable manner.A minimum working temperature of 0°C is required for this isolated switch.Due to the fact that it has a 200mA output current, it offers maximum design flexibility.The output voltage of the AC to DC power converter is 13.5V .
