UC3843D 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 solid enclosure protects the pmic. The system can process Transistor Driver dc switching's outputs (s). The supply and operating voltage of the dc control are 12V~28V. Workable in an dc switcher where 0°C~70°C TA is the 0°C~70°C TArm. There is a switch at Up to 500kHz that can be used with this controller. The Surface Mount value makes it suitable for general dc dc regulator. Frequency Control provides dcdc regulator efficient switching control. The switch converters are connected to an analog IC with a SWITCHING CONTROLLER output. DUAL are the position of the terminal of the switching converters. 14 terminations with various dc switching's functions. This dc dc converter ic uses a variety of control techniques, including PULSE WIDTH MODULATION. DC switcher's input voltageis set to 15V. Searching "UC3843" will return other relevant dc to dc converter ics. Total pins of switching converter are 14. The type is a particular Switching Regulator or Controllers of switching converter. As determined by the test statistics, the output voltage of DC regulator is 13.5V. normally, the dc dc regulator's output current is 200mA, which you should keep in mind when starting a project. Voltage regulator dc to dc is designed to operate at 100 % duty cycle during power-ups and power-downs to ensure reliability. Switching controller operates at a frequency of 450kHz. As long as the dc switching is in a dormant state, it utilizes 11mA. A nominal working status is achieved when the input voltage is set to 25V. It is not recommended to supply more current to the controller than 25mA. An input of 11mA current flow could satisfy the operation of the switching converter .
