UC3843DTR Overview
It comes in the 14-SOIC (0.154, 3.90mm Width) package, which makes switching controller suitable for most applications. dc motor controller is suitable for 1 output generation. There is a Tape & Reel (TR) solid enclosure around the pmic. There are Transistor Driver dc switching's output (s) that it can handle. dc controls with 12V~28V voltage are supplied and operated. Qualified to work in a 0°C~70°C TA dc switcher. Using this switching controller, it is possible to switch at Up to 500kHz. Surface Mount makes it suitable for general dc dc regulator. Featured in the dcdc regulator is Frequency Control which allows efficient switching control. Thare switch converters are connected to an analog integrated circuit (IC) of type SWITCHING CONTROLLER. Switching converters are designed with the terminal (s) at position DUAL . Various 14 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. UC3843 can be used to locate other relevant dc to dc converter ics. There are 14 pins on switching converter. Switching converter type is specifically Switching Regulator or Controllers. Statistically, the DC regulator outputs 13.5V voltage. The dc dc regulator's usual output current is 200mA, 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. Switching controller operates at 450kHz Hz. A nominal working status is achieved when the input voltage is set to 25V. There should be 25mA current exceeding 25mA supplied to the controller.
