UC3843ADTR Overview


Capsuled in the 14-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. Packaged in solid enclosures, this pmic has a Tape & Reel (TR) rating. Transistor Driver dc switching's outputs (s) can be handled by it. The supply and operating voltage of the dc control are 7.6V~30V. Suitable for work in a 0°C~70°C TA dc switcher. In this switching controller, the switch can be set to Up to 500kHz. The Surface Mount allows it to be used for dc dc regulator in general. In order to control switching efficiently, the dcdc regulator features Frequency Control. Switch converters are connected to ICs with SWITCHING CONTROLLER analog outputs. Thare switching converters has a terminal (s) at DUAL . Various 14 terminations. These dc dc converter ics adapt a variety of control techniques, including PULSE WIDTH MODULATION. DC switcher's voltage input is 15V. Other relevant dc to dc converter ics can be found by searching "UC3843". There are 14 pins on switching converter. The type is a particular Switching Regulator or Controllers of switching converter. Based on the test statistics, DC regulator outputs voltage 15V. A starting point for a project is to note down the dc dc regulator's usual output current, which is 200mA. voltage regulator dc to dcs with a 100 % duty cycle are designed to be reliable when powered on and powered off. Switching controllers work at 450kHz Hz. You can set the input voltage to 25V for nominal working status. The supply voltage should be 11V. Current supplied to the controller should not exceed 25mA.
