UC3843D8TRG4 Overview
Capsuled in the 8-SOIC (0.154, 3.90mm Width) package, the switching controller can be used for a wide range of applications. This dc motor controller can be used to generate outputs with 1 numbers. Packaging for the pmic consists of Tape & Reel (TR) solid enclosures. With this function, you can deal with Transistor Driver dc switching's outputs (s). Voltages 12V~28V are the dc control's supply voltage and operating voltage, respectively. Worked in a 0°C~70°C TA dc switcher before. With this switching controller, you can switch at Up to 500kHz. The Surface Mount makes it ideal for general dc dc regulator. To ensure efficient switching, this dcdc regulator features a Frequency Control. An analog IC with the SWITCHING CONTROLLER signal is connected to the switch converters. A switching converters's terminal (s) sits at the DUAL position. An array of 8 terminations of dc switching. This dc dc converter ic uses a variety of control techniques, including PULSE WIDTH MODULATION. There is a DC switcher's nominal voltage of 15V. In addition to "UC3843", there are other relevant dc to dc converter ics you can find. There are a total of 8 pins on switching converter. Specifically, switching converter falls under the Switching Regulator or Controllers category. Based on the test statistics, DC regulator outputs voltage 13.5V. A starting point for a project is to note down the dc dc regulator's usual output current, which is 200mA. A duty cycle set at 100 % ensures voltage regulator dc to dc reliability during power-on and power-off. Switching controller operates at a frequency of 450kHz. It is possible to set the input voltage as 25V for nominal working statuses. There should be 25mA more than 25mA amps of current supplied to the controller.
