SG3843DM Overview
This switching controller fits most application requirements since it is packaged in a 8-SOIC (0.154, 3.90mm Width) package. There is enough capacity in the dc motor controller to generate the output for the 1 input. Packaged in solid enclosures, this pmic has a Tube rating. The program can handle Transistor Driver dc switching's outputs (s). dc controls with 7.6V~30V voltage are supplied and operated. Suitable for work in a 0°C~70°C TA dc switcher. This switching controller can switch at 1Hz~500kHz. It is suitable for general dc dc regulator when it is set to Surface Mount. A SWITCHING CONTROLLER analog IC is connected to the switch converters. There are a terminal (s) on the switching converters that are designed at DUAL. A variety of 8 terminations are available in dc switching. To name a few of the control techniques these dc dc converter ics adapt, it includes PULSE WIDTH MODULATION. The DC switcher's nominal voltage is 15V. In addition to "SG*843", there are other relevant dc to dc converter ics you can find. Total pins of switching converter are 8. In particular, switching converter is a type of Switching Regulator or Controllers. Voltages 25V are the maximum that the dc to dc regulator will accept. You should note down the dc dc regulator's usual output current of 200mA when you start a project. It is set to 100 % duty cycle to ensure voltage regulator dc to dc reliability during power-ups and power-downs. As DC switcher has a Surface Mount, it's suitable for most applications and prototype designs. Switching controllers operate at 500kHz frequencies. Users should apply 30V to operate the voltage regulator dc to dc safely and reliably. In dormant mode, 11mA is used.
