UC2843D8G4 Overview


It comes in the 8-SOIC (0.154, 3.90mm Width) package, which makes switching controller suitable for most applications. This dc motor controller can be used to generate outputs with 1 numbers. PMIC packaging is solid with a Tube enclosure. A total of Transistor Driver dc switching's outputs can be handled by it. Voltages 12V~28V are the dc control's supply voltage and operating voltage, respectively. Qualified to work in a -40°C~85°C TA dc switcher. Switching can be done at Up to 500kHz with this switching controller. As it has a Surface Mount value, it can be used for general dc dc regulator. Frequency Control provides dcdc regulator efficient switching control. The switch converters are connected to a SWITCHING CONTROLLER analog IC. Terminal (s) of the switching converters are designed at the DUAL position. The 8 terminations can be used for a wide range of dc switching. These dc dc converter ics adapt a variety of control techniques, including PULSE WIDTH MODULATION. DC switcher's input voltageis set to 15V. A search for "UC2843" will reveal other relevant dc to dc converter ics. There are a total of 8 pins on switching converter. The type is a particular Switching Regulator or Controllers of switching converter. A 13.5V voltage of DC regulator was detected in the test statistics. You should note that the dc dc regulator's usual output current is 200mA. Power-up and power-down reliability is ensured voltage regulator dc to dc by setting the maximum duty cycle to 100 %. A frequency of 500kHz is set for the switching controller. You can set the input voltage to 25V for nominal working status. It is not recommended to supply more current to the controller than 25mA. For operation, the switching converter could be satisfied with 11mA current flow input.
