UC2843D Overview


Capsuled in the 14-SOIC (0.154, 3.90mm Width) package, the switching controller suits most application needs. dc motor controller is suitable for 1 output generation. PMIC packaging is solid with a Tube enclosure. It is capable of dealing with Transistor Driver dc switching's output (s). dc switching'sdc controls with 12V~28V voltage are supplied and operated. Worked in a -40°C~85°C TA dc switcher before. There is a switch at Up to 500kHz that can be used with this controller. Surface Mount makes it suitable for general dc dc regulator. Featured in the dcdc regulator is Frequency Control which allows efficient switching control. A SWITCHING CONTROLLER analog integrated circuit is connected to the switch converters. DUAL are the position of the terminal of the switching converters. A variety of 14 terminations are available in dc switching. It includes PULSE WIDTH MODULATION as one of the control techniques dc dc converter ic adapts. DC switcher's voltage input is 15V. You can find other relevant dc to dc converter ics by searching "UC2843". Total pins of switching converter are 14. The type is a particular Switching Regulator or Controllers of switching converter. The test statistics indicate that DC regulator outputs a voltage of 13.5V. It's important to remember that the dc dc regulator's normaloutput current is 1A, 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. The switching controller works at a frequency of 450kHz. It is possible to set the input voltage to 25V for nominal working status. Current supplied to the controller should not exceed 25mA.
