SG3844DM Overview
It is embedded in package 8-SOIC (0.154, 3.90mm Width) .In Bulk case, the ac dc converter is available.A AC/DC converter of this type is mounted in the way of Surface Mount .The ac dc converter should be operated at a temperature of 0°C~70°C TA °C to deliver its optimal performance.The AC DC converter uses a type SWITCHING CONTROLLER analog integrated circuit.As a result, the switching frequency reaches 100Hz~500kHz .Vcc/Vdd can be used within the range of 10V~30V supply voltage.It has a total of 8 terminations.Approximately 8 pins are present on the ac/dc converter.In this ac-dc converter, there are 8 pins.The ac dc converters are suitable to mount by Surface Mount .Similar acdc converters can be found using the SG*844 family.A total of 1 outputs are available for processing.Switching Regulator or Controllers contains the ac to dc conversions.200mA is set as the output current.As long as AC to DC converter is operated at frequency 500kHz ,it is capable of attaining high efficiency.Based on a unique technique, the input voltage can be ensured to have the maximal value of 25V .At 30V supply voltage, the interface IC conducts.The system consumes quiescent current at 11mA .
