UC2845D Overview


The switching controller fits in the 14-SOIC (0.154, 3.90mm Width) package and is ideal for most applications. There is sufficient capacity to generate switching controller for outputs 1. PMIC is packaged in a solid enclosure of Tube. The program can handle Transistor Driver dc switching's outputs (s). A 12V~28V voltage is supplied to the dc control and used for operating it. Suitable for work in a -40°C~85°C TA dc switcher. The Surface Mount value makes it suitable for general dc dc regulator. To provide efficient switching control, Frequency Control is included in the dcdc regulator. The switch converters are connected to a SWITCHING CONTROLLER analog IC. Switching converters are designed with the terminal (s) at position DUAL . A variety of dc switching's functions can be performed on 14 terminations. Some of the control techniques adapted by these dc dc converter ics include PULSE WIDTH MODULATION. 15V nominal DC switcher's voltage input. You can find other relevant dc to dc converter ics by searching "UC2845". There are a total of 14 pins on switching converter. Particularly, switching converter is a type of Switching Regulator or Controllers. Test statistics indicate DC regulator outputs 13.5V voltage. You should note that the dc dc regulator's usual output current is 200mA. It is set to 50 % duty cycle to ensure voltage regulator dc to dc reliability during power-ups and power-downs. A frequency of 500kHz is used by the switching controller. For nominal working status, the input voltage can be set as 25V. The controller should not be supplied with more current than 25mA. The supply current of the voltage controller is 11mA. For this the controllers dc, the nominal current supply is 17mA. 11mA current flow input could satisfy the switching converter for operation.
