    Products Detail

    SG3843DM Overview


    It comes in the 8-SOIC (0.154, 3.90mm Width) package, which makes switching controller suitable for most applications. It is sufficient to generate 1 outputs with this dc motor controller. Packaging for the pmic consists of Tube solid enclosures. The program can handle Transistor Driver dc switching's outputs (s). dc control's supply and operating voltages are 7.6V~30V. Qualified to work in an dc switcher with 0°C~70°C TA. The switching controller can be switched at 1Hz~500kHz. dc dc regulators can be carried out with Surface Mount. The switch converters are connected to an analog IC with a SWITCHING CONTROLLER output. There are a DUAL terminal on the switching converters. Different dc switching's functions can be applied to 8 terminations. Some of the control techniques adapted by these dc dc converter ics include PULSE WIDTH MODULATION. DC switcher's voltage input of 15V. SG*843 can be searched for other relevant dc to dc converter ics. In total, switching converter has 8 pins. Switching converter type is specifically Switching Regulator or Controllers. This dc to dc regulator accepts only 25V input voltage at most. In most cases, the output current of the dc dc regulator will be 200mA, so note that when you start the project. Power-up and power-down reliability is ensured voltage regulator dc to dc by setting the maximum duty cycle to 100 %. DC switcher's Surface Mount qualifies it for most applications and prototypes. 500kHz is the frequency of the switching controller. For safe and reliable operation in a circuit, voltage regulator dc to dc is suggested that users apply 30V. Dormant dc switchings use 11mA.
