SG2844DM Overview
It is embedded in package SOIC .In Bulk AC/DC power converter, it is available.Surface Mount mounts this AC/DC converter.The ac dc converter should be operated at a temperature of -25°C~85°C TA °C to deliver its optimal performance.In this AC DC converter, the analog IC type is SWITCHING CONTROLLER .There is 100Hz~500kHz switching frequency.Within the range of 10V~30V supply voltage (Vcc/Vdd), it can be used.There are a total of 8 terminations.On this ac/dc converter, there are 8 pins.The pins of the ac-dc converter total to 8 .The ac dc converters is suitable for mounting by Surface Mount .If you select the SG*844 family, you will be able to search for similar acdc converters.There are 1 outputs to be run.The ac to dc conversions are contained in Switching Regulator or Controllers .We are setting the output current to 200mA .As a result, its output voltage is 13.5V .AC to DC converter is able to reach high efficiency when its frequency is 500kHz .Using a unique technique, a voltage with a maximum value of 25V can be ensured.When the supply voltage is 30V , the interface IC conducts.In addition, it is included in the 8-SOIC package.The system consumes quiescent current at 11mA .
