UC3846DWTR Overview


Capsuled in the 16-SOIC (0.295, 7.50mm 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 2 input. Packaged in solid enclosures, this pmic has a Tape & Reel (TR) rating. A total of Transistor Driver dc switching's outputs can be handled by it. DC control operates at 6.95V~40V volts and has 6.95V~40V supply voltage. Workable in an dc switcher where 0°C~70°C TA is the 0°C~70°C TArm. Switching can be done at 500kHz with this switching controller. As it has a Surface Mount value, it can be used for general dc dc regulator. Featured in the dcdc regulator is Current Limit, Enable, Frequency Control, Soft Start which allows efficient switching control. A SWITCHING CONTROLLER analog integrated circuit is connected to the switch converters. Terminal (s) of the switching converters are designed at the DUAL position. A variety of 16 terminations are available in dc switching. This dc dc converter ic uses a variety of control techniques, including PULSE WIDTH MODULATION. It is inputted with a DC switcher's voltage of 15V. You can find other relevant dc to dc converter ics by searching "UC3846". There are a total of 16 pins on switching converter. In particular, switching converter belongs to the Switching Regulator or Controllers family. As determined by the test statistics, the output voltage of DC regulator is 13.5V. It's important to remember that the dc dc regulator's normaloutput current is 500mA, so you should note it down when starting a new project. A duty cycle set at 50 % ensures voltage regulator dc to dc reliability during power-on and power-off. A frequency of 450kHz is used by the switching controller. A nominal working status is achieved when the input voltage is set to 15V.
