UC3843ANG4 Overview


Capsuled in the 8-DIP (0.300, 7.62mm) package, the switching controller can be used for a wide range of applications. The dc motor controller is adquate to generate for 1 outputs. Packaged in solid enclosures, this pmic has a Tube rating. With Transistor Driver dc switching's output (s), it is able to handle it. dc controls with 7.6V~30V voltage are supplied and operated. Qualified to work in an dc switcher with 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 Through Hole. Frequency Control provides dcdc regulator efficient switching control. A SWITCHING CONTROLLER analog IC is connected to the switch converters. DUAL are the position of the terminal of the switching converters. A variety of terminations with 8 of dc switching. The control methods that these dc dc converter ics use include PULSE WIDTH MODULATION. A DC switcher's nominal voltage of 15V is input. A search for "UC3843" will reveal other relevant dc to dc converter ics. In total, switching converter has 8 pins. Switching converter is a special type of Switching Regulator or Controllers. DC regulator outputs 15V voltage according to the test statistics. You should note that the dc dc regulator's usual output current is 200mA. Power-up and power-down reliability is ensured voltage regulator dc to dc by setting the maximum duty cycle to 100 %. Switching controller operates at 450kHz Hz. It is possible to set the input voltage to 25V for nominal working status. A supply voltage of 11V is required. There should be 25mA current exceeding 25mA supplied to the controller.
