UC2847DWG4 Overview


Capsuled in the 16-SOIC (0.295, 7.50mm Width) package, the switching controller can be used for a wide range of applications. For 2 outputs, the dc motor controller is appropriate. Packaged in solid enclosures, this pmic has a Tube rating. A total of Transistor Driver dc switching's outputs can be handled by it. Voltages 6.95V~40V are the dc control's supply voltage and operating voltage, respectively. Suitable for work in a -40°C~85°C TA dc switcher. With this switching controller, you can switch at 500kHz. 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. An analog IC with the SWITCHING CONTROLLER signal is connected to the switch converters. DUAL are the position of the terminal of the switching converters. There are many different types of terminations for 16. Some of the control techniques used by these dc dc converter ics are PULSE WIDTH MODULATION. DC switcher's voltage input of 15V. Search for "UC2847" to find other relevant dc to dc converter ics. Switching converter has a total of 16 pins. Switching converter type is specifically Switching Regulator or Controllers. Statistically, the DC regulator outputs 13.5V voltage. A starting point for a project is to note down the dc dc regulator's usual output current, which is 500mA. It is set to 50 % duty cycle to ensure voltage regulator dc to dc reliability during power-ups and power-downs. 450kHz is the frequency of the switching controller. It is possible to set the input voltage to 15V for nominal working status. There is a requirement for a 15V supply voltage.
