UC3846DWTRG4 Overview


In the 16-SOIC (0.295, 7.50mm Width) package, the switching controller meets most application requirements. For 2 outputs, the dc motor controller is appropriate. Tape & Reel (TR) solid enclosure protects the pmic. Transistor Driver dc switching's outputs (s) can be handled by it. dc control's supply and operating voltages are 6.95V~40V. Worked in an dc switcher with a 0°C~70°C TA rating. It can switch at 500kHz. dc dc regulators can be carried out with Surface Mount. In order to control switching efficiently, the dcdc regulator features Current Limit, Enable, Frequency Control, Soft Start. SWITCHING CONTROLLER analog IC connects the switch converters. The switching converters's terminals (s) are designed at DUAL. A variety of dc switching's functions can be performed on 16 terminations. It includes PULSE WIDTH MODULATION as one of the control techniques dc dc converter ic adapts. The DC switcher's nominal voltage is 15V. UC3846 can be used to locate other relevant dc to dc converter ics. 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. You should note down the dc dc regulator's usual output current of 500mA when you start a project. As a result of this, the maximum duty cycle of the voltage regulator dc to dc must remain 50 % during power-up and power-down. Switching controllers work at 450kHz Hz. It is possible to set the input voltage to 15V for nominal working status.
