UC3856QG3 Product Details

UC3856QG3 Overview


Capsuled in the 20-LCC (J-Lead) 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. PMIC packaging is solid with a Tube enclosure. A total of Transistor Driver dc switching's outputs can be handled by it. Voltages 7V~40V are the dc control's supply voltage and operating voltage, respectively. Work well in dc switchers with a 0°C~70°C TA. Using this switching controller, it is possible to switch at 200kHz. A generalization of dc dc regulator can be made using Surface Mount. To ensure efficient switching, this dcdc regulator features a Enable, Frequency Control, Soft Start. An analog IC with the SWITCHING CONTROLLER signal is connected to the switch converters. A switching converters's terminal (s) sits at the QUAD position. A variety of dc switching's functions can be performed on 20 terminations. The control methods that these dc dc converter ics use include PULSE WIDTH MODULATION. DC switcher's voltage input is 15V. You can find other relevant dc to dc converter ics by searching "UC3856". Pins number 20 of switching converter in total. Specially, switching converter corresponds to type Switching Regulator or Controllers. Test statistics indicate DC regulator outputs 13.1V voltage. In most cases, the dc dc regulator's output current is 200mA. This information should be noted when you begin working with the component. 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 controller operates at 1MHz Hz. It is possible to set the input voltage as 40V for nominal working statuses.
