UC2843AD8TRG4 Product Details
UC2843AD8TRG4 Overview
The switching controller fits in the 8-SOIC (0.154, 3.90mm Width) package and is ideal for most applications. For outputs of 1, this dc motor controller is suitable. Tape & Reel (TR) solid enclosure protects the pmic. The program can handle Transistor Driver dc switching's outputs (s). The supply and operating voltage of the dc control are 7.6V~30V. Work well in dc switchers with a -40°C~85°C TA. The switching controller can be switched at Up to 500kHz. dc dc regulator can be generalized using Surface Mount. To provide efficient switching control, Frequency Control is included in the dcdc regulator. A SWITCHING CONTROLLER analog IC is connected to the switch converters. There are a DUAL terminal on the switching converters. There are many different types of terminations for 8. Some of the control techniques used by these dc dc converter ics are PULSE WIDTH MODULATION. A DC switcher's nominal voltage of 15V is input. Other relevant dc to dc converter ics will be returned if you search "UC2843". 8 pins are on switching converter. Switching converter is a type of Switching Regulator or Controllers in particular. As determined by the test statistics, the output voltage of DC regulator is 15V. A starting point for a project is to note down the dc dc regulator's usual output current, which is 200mA. The maximum duty cycle of this voltage regulator dc to dc is set to 100 % to ensure reliability during power-up and power-down. There is 450kHz frequency setting on the switching controller. A nominal working status is achieved when the input voltage is set to 25V. Switching controller is necessary to provide a voltage of 11V. 25mA more than 25mA current should be supplied to the controller.
