UC2843DG4 Product Details
UC2843DG4 Overview
As a result of 14-SOIC (0.154, 3.90mm Width) compact design, the switching controller is compatible with most applications. 1 outputs are supported by the dc motor controller. There is a Tube solid enclosure around the pmic. Transistor Driver dc switching's outputs (s) can be handled by it. 12V~28V is the supply voltage and the operating voltage of the dc control. Qualified to work in an dc switcher with -40°C~85°C TA. Using this switching controller, it is possible to switch at Up to 500kHz. The Surface Mount makes it ideal for general dc dc regulator. DCDC regulator is controlled efficiently by Frequency Control. A SWITCHING CONTROLLER analog IC is connected to the switch converters. The switching converters's terminal (s) are designed at DUAL . A variety of terminations with 14 of dc switching. A few of the control techniques these dc dc converter ics adapt include PULSE WIDTH MODULATION. 15V nominal DC switcher's voltage input. Other relevant dc to dc converter ics can be found by searching "UC2843". Switching converter has a total of 14 pins. Switching converter type is specifically Switching Regulator or Controllers. As determined by the test statistics, the output voltage of DC regulator is 13.5V. In most cases, the output current of the dc dc regulator will be 200mA, so note that when you start the project. Voltage regulator dc to dc is designed to operate at 100 % duty cycle during power-ups and power-downs to ensure reliability. The switching controller works at a frequency of 450kHz. It is possible to set the input voltage as 25V for nominal working statuses. You should not supply more current than 25mA to the controller.
