UC3886N Overview
Capsuled in the 16-DIP (0.300, 7.62mm) package, the switching controller can be used for a wide range of applications. For outputs of 1, this dc motor controller is suitable. Tube solid enclosure protects the pmic. The system can process Transistor Driver dc switching's outputs (s). This dc control has a supply voltage and operating voltage of 10.3V~20V. Work well in dc switchers with a 0°C~70°C TA. In this switching controller, the switch can be set to Up to 300kHz. dc dc regulator can be generalized using Through Hole. For efficient switching control, the dcdc regulator features Enable, Frequency Control. A SWITCHING CONTROLLER analog integrated circuit is connected to the switch converters. Thare switching converters has a terminal (s) at DUAL . 16 terminations with a variety of function. These dc dc converter ics adapt several control methods, including PULSE WIDTH MODULATION. 12V nominal DC switcher's voltage input. A search for "UC3886" will reveal other relevant dc to dc converter ics. Switching converter has a total of 16 pins. Specially, switching converter corresponds to type Switching Regulator or Controllers. Test statistics indicate DC regulator outputs 10.3V voltage. Considering the dc to dc regulator can only accept 20V input voltage, it is important to take note of this. In most cases, the output current of the dc dc regulator will be 200mA, so note that when you start the project. Voltage regulator dc to dc is designed to operate at 90 % duty cycle during power-ups and power-downs to ensure reliability. A frequency of 400kHz is set for the switching controller.
