UC3847N Overview
With a 16-DIP (0.300, 7.62mm) package, the switching controller is suitable for a wide range of applications. For 2 outputs, the dc motor controller is appropriate. Packaging for the pmic consists of Tube solid enclosures. Transistor Driver dc switching's outputs (s) can be handled by it. A 6.95V~40V voltage is supplied to the dc control and used for operating it. Workable in an dc switcher where 0°C~70°C TA is the 0°C~70°C TArm. The Through Hole value makes it suitable for general dc dc regulator. To provide efficient switching control, Current Limit, Enable, Frequency Control, Soft Start is included in the dcdc regulator. A SWITCHING CONTROLLER analog IC is connected to the switch converters. DUAL are the position of the terminal of the switching converters. Different dc switching's functions can be applied to 16 terminations. It includes PULSE WIDTH MODULATION as one of the control techniques dc dc converter ic adapts. DC switcher's input voltageis 15V volts. Other relevant dc to dc converter ics can be found by searching "UC3847". Switching converter has a total of 16 pins. The type is a particular Switching Regulator or Controllers of switching converter. Statistically, DC regulator outputs 13.5V volts. 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. During power-up and power-down, the maximum duty cycle of the voltage regulator dc to dc is set to 50 %. There is 500kHz frequency setting on the switching controller. DC switching uses 17mA when it is dormant. You can set the input voltage to 15V for nominal working status.
