UC3843N Overview
In the 8-DIP (0.300, 7.62mm) package, the switching controller meets most application requirements. This dc motor controller can be used to generate outputs with 1 numbers. Tube is the solid enclosure in which PMIC is packaged. With this function, you can deal with Transistor Driver dc switching's outputs (s). This dc control has a supply voltage and operating voltage of 12V~28V. Worked in a 0°C~70°C TA dc switcher before. With this switching controller, you can switch at Up to 500kHz. The Through Hole makes it ideal for general dc dc regulator. Frequency Control provides dcdc regulator efficient switching control. Connected to a SWITCHING CONTROLLER analog IC, the switch converters are connected to a power supply. There are a DUAL terminal on the switching converters. Different dc switching's functions can be applied to 8 terminations. To name a few of the control techniques these dc dc converter ics adapt, it includes PULSE WIDTH MODULATION. A DC switcher's nominal voltage of 15V is input. Other relevant dc to dc converter ics will be returned if you search "UC3843". Pins number 8 of switching converter in total. Switching converter type is specifically Switching Regulator or Controllers. Based on the test statistics, DC regulator outputs voltage 13.5V. The dc dc regulator's usual output current is 1A, which should be noted down when you start a project. A duty cycle set at 100 % ensures voltage regulator dc to dc reliability during power-on and power-off. In most applications and prototype designs, DC switcher is qualified as a Through Hole. Switching controller operates at a frequency of 450kHz. In dormant mode, 11mA is used. It is possible to set the input voltage to 25V for nominal working status. A controller's current should not exceed 25mA.
