KA3843BD Overview
The switching controller fits in the 14-SOIC (0.154, 3.90mm Width) package and is ideal for most applications. 1 outputs are supported by the dc motor controller. Tube is the solid enclosure in which PMIC is packaged. With Transistor Driver dc switching's output (s), it is able to handle it. DC control operates at 7.6V~30V volts and has 7.6V~30V supply voltage. Suitable for work in a 0°C~70°C TA dc switcher. The switching controller can be switched at Up to 500kHz. As it has a Surface Mount value, it can be used for general dc dc regulator. The switch converters are connected to an analog IC with a SWITCHING CONTROLLER output. Thare switching converters has a terminal (s) at DUAL . A variety of terminations with 14 of dc switching. PULSE WIDTH MODULATION is an example of one of the control techniques these dc dc converter ics adapt. It is inputted with a DC switcher's voltage of 15V. Other relevant dc to dc converter ics can be found by searching "KA3843". There are 14 pins on switching converter. It is recommended to use 8.2V as the minimum input voltage of dc dc voltage regulator. The dc to dc regulator is limited to 25V input voltage. You should note down the dc dc regulator's usual output current of 1A when you start a project. Power-up and power-down reliability is ensured voltage regulator dc to dc by setting the maximum duty cycle to 100 %. The Surface Mount makes DC switcher suitable for most applications and prototypes. There is a maximum frequency of 500kHz for this dc regulators. Overall, the switch converters contains 1 function(s). 17mA volts is the supply current.
