UC2843AQDR Overview
It comes in a 14-SOIC (0.154, 3.90mm Width) package, so switching controller can be used for most applications. For 1 outputs, the dc motor controller is appropriate. A solid enclosure of Cut Tape (CT) surrounds pmic. It is capable of dealing with Transistor Driver dc switching's output (s). dc switching'sThe supply and operating voltage of the dc control are 7.6V~30V. Work well in dc switchers with a -40°C~125°C TA. With this switching controller, you can switch at Up to 500kHz. As it has a Surface Mount value, it can be used for general dc dc regulator. Switching control is made easier with the dcdc regulator's Frequency Control. An analog IC SWITCHING CONTROLLER is connected to the switch converters. There are a DUAL terminal on the switching converters. An array of 14 terminations 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. You can find other relevant dc to dc converter ics by searching "UC2843". There are a total of 14 pins on switching converter. In particular, switching converter is a type of Switching Regulator or Controllers. According to the test statistics, DC regulator outputs 15V voltage. It should be fully noted that the dc to dc regulator only accepts 25V input voltage at most. It's important to remember that the dc dc regulator's normaloutput current is 200mA, so you should note it down when starting a new project. A duty cycle set at 100 % ensures voltage regulator dc to dc reliability during power-on and power-off. 500kHz is the frequency of the switching controller. There are several dc to dc voltage regulator in the Automotive, AEC-Q100 series. When the dc switching is dormant, it uses 11mA.
