UC3842D8G4 Product Details

UC3842D8G4 Overview


There is a ac to dc converter embedded in package SOIC .In this AC DC converter, an analog integrated circuit (IC) of type SWITCHING CONTROLLER is employed.When the switching frequency reaches 500kHz , the process is complete.There are a total of 8 terminations in it.It contains 8 pins.The ac-dc converter has 8 pins.AC to DC converter is necessary to run 1 outputs.AC to DC converter is contained in Switching Regulator or Controllers .The voltage output by this AC/DC converter is 5V .This power AC DC is capable of reaching high efficiencies when operating at a frequency of 450kHz .Using 70°C as the maximum ensures that the AC to DC power converter operates in a stable manner.Minimum working temperature of this isolated switch must not be lower than 0°C .It has a 200mA output current, allowing maximum design flexibility.As a result, the output voltage is 13.5V .
