UC3843D8G4 Overview


Capsuled in the 8-SOIC (0.154, 3.90mm Width) package, the switching controller suits most application needs. dc motor controller is suitable for 1 output generation. PMIC is packaged in a solid enclosure of Tube. Transistor Driver dc switching's outputs (s) can be handled by it. DC control operates at 12V~28V volts and has 12V~28V supply voltage. Worked in an dc switcher with a 0°C~70°C TA rating. The switching controller is capable of switching at the Up to 500kHz position. It is suitable for general dc dc regulator when it is set to Surface Mount. Featured in the dcdc regulator is Frequency Control which allows efficient switching control. The switch converters are connected to a SWITCHING CONTROLLER analog IC. The switching converters's terminal (s) are designed at DUAL . There are many different types of terminations for 8. Some of the control techniques adapted by these dc dc converter ics include PULSE WIDTH MODULATION. DC switcher's voltage input is 15V. You can find other relevant dc to dc converter ics by searching "UC3843". In total, switching converter has 8 pins. Switching converter type is specifically Switching Regulator or Controllers. Based on the test statistics, DC regulator outputs voltage 13.5V. The dc dc regulator's usual output current is 200mA, which should be noted down when you start a project. Power-up and power-down reliability is ensured voltage regulator dc to dc by setting the maximum duty cycle to 100 %. There is 450kHz frequency setting on the switching controller. It is possible to set the input voltage to 25V for nominal working status. It is not recommended to supply more current to the controller than 25mA.
