UC2845DG4 Product Details

UC2845DG4 Overview


It comes in the 14-SOIC (0.154, 3.90mm Width) package, which makes switching controller suitable for most applications. 1 outputs are supported by the dc motor controller. A solid enclosure of Tube surrounds pmic. It is capable of dealing with Transistor Driver dc switching's output (s). dc switching'sA 12V~28V voltage is supplied to the dc control and used for operating it. Worked in a -40°C~85°C TA dc switcher before. A generalization of dc dc regulator can be made using Surface Mount. The dcdc regulator features Frequency Control for efficient switching control. Thare switch converters are connected to an analog integrated circuit (IC) of type SWITCHING CONTROLLER. The switching converters's terminals (s) are designed at DUAL. A variety of dc switching's functions can be performed on 14 terminations. It includes PULSE WIDTH MODULATION as one of the control techniques dc dc converter ic adapts. The DC switcher's nominal voltage is 15V. In addition to "UC2845", there are other relevant dc to dc converter ics you can find. Pins number 14 of switching converter in total. Switching converter type is specifically Switching Regulator or Controllers. A 13.5V voltage of DC regulator was detected in the test statistics. In most cases, the dc dc regulator's output current is 200mA. This information should be noted when you begin working with the component. It is set to 50 % duty cycle to ensure voltage regulator dc to dc reliability during power-ups and power-downs. Switching controllers work at 500kHz Hz. 25V is the nominal working voltage. In order to limit the voltage of a dc switcher whose maximum input voltage is 25V, it must be limited by the user. There will be 1A output current greater than 1A from the dc switcher. A controller's current should not exceed 25mA. An input flow rate of 11mA could satisfy the switching converter 's operation requirements.
