UC3843D8 Product Details
UC3843D8 Overview
Capsuled in the 8-SOIC (0.154, 3.90mm Width) package, the switching controller can be used for a wide range of applications. There is enough capacity in the dc motor controller to generate the output for the 1 input. PMIC packaging is solid with a Tube enclosure. A total of Transistor Driver dc switching's outputs can be handled by it. Voltages 12V~28V are the dc control's supply voltage and operating voltage, respectively. Work well in dc switchers with a 0°C~70°C TA. Using this switching controller, it is possible to switch at Up to 500kHz. A generalization of dc dc regulator can be made using Surface Mount. 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. A variety of dc switching's functions can be performed on 8 terminations. The control methods that these dc dc converter ics use include PULSE WIDTH MODULATION. DC switcher's voltage input is 15V. You can find other relevant dc to dc converter ics by searching "UC3843". Pins number 8 of switching converter in total. Specially, switching converter corresponds to type Switching Regulator or Controllers. Test statistics indicate DC regulator outputs 5V voltage. In most cases, the dc dc regulator's output current is 200mA. This information should be noted when you begin working with the component. As a result of this, the maximum duty cycle of the voltage regulator dc to dc must remain 100 % during power-up and power-down. Switching controller operates at 450kHz Hz. A dc switching in a dormant state uses 11mA. It is possible to set the input voltage as 15V for nominal working statuses. There should be 25mA current exceeding 25mA supplied to the controller. A current of 11mA is supplied to it. If there is 11mA current flow input, then the switching converter could operate.
