KA3843B Overview


It comes in the 8-DIP (0.300, 7.62mm) package, which makes switching controller suitable for most applications. 1 outputs are supported by the dc motor controller. PMIC packaging is solid with a Tube enclosure. It is capable of dealing with Transistor Driver dc switching's output (s). dc switching'sVoltages 7.6V~30V are the dc control's supply voltage and operating voltage, respectively. Suitable for working in an dc switcher that has a 0°C~70°C TA. Switching can be done at Up to 500kHz with this switching controller. dc dc regulator is made easier with Through Hole. Thare switch converters are connected to an analog integrated circuit (IC) of type SWITCHING CONTROLLER. DUAL are the position of the terminal of the switching converters. Various 8 terminations. Some of the control techniques adapted by these dc dc converter ics include PULSE WIDTH MODULATION. DC switcher's input voltageis set to 15V. KA3843 can be searched for other relevant dc to dc converter ics. Switching converter has a total of 8 pins. Particularly, switching converter is a type of Switching Regulator or Controllers. DC regulator outputs 5V voltage based on test statistics. If you start a project, note down the dc dc regulator's usual output current of 200mA. Voltage regulator dc to dc is designed to operate at 100 % duty cycle during power-ups and power-downs to ensure reliability. DC switcher's Through Hole makes it qualified for most application and prototype designs. DC switcher'sSwitching controllers operate at 500kHz frequencies. In total, the switch converters have 1 function (s). You can set the input voltage to 15V for nominal working status. 17mA volts is the supply current. A current greater than 17mA may result in improper operation and possibly damage to the component.
