UC2843DTR Overview


The switching controller fits in the 14-SOIC (0.154, 3.90mm Width) package and is ideal for most applications. The dc motor controller is adquate to generate for 1 outputs. The pmic is packaged in Tape & Reel (TR) solid enclosure. With Transistor Driver dc switching's output (s), it is able to handle it. dc control's supply and operating voltages are 12V~28V. Workable in an dc switcher where -40°C~85°C TA is the -40°C~85°C TArm. It can switch at Up to 500kHz. The Surface Mount allows it to be used for dc dc regulator in general. To provide efficient switching control, Frequency Control is included in the dcdc regulator. SWITCHING CONTROLLER analog IC connects the switch converters. Terminal (s) of the switching converters are designed at the DUAL position. Various 14 terminations. The control methods that these dc dc converter ics use include PULSE WIDTH MODULATION. DC switcher's input voltageis 15V volts. 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. DC regulator outputs 13.5V voltage according to the test statistics. If you start a project, note down the dc dc regulator's usual output current of 200mA. Power-up and power-down reliability is ensured voltage regulator dc to dc by setting the maximum duty cycle to 100 %. Switching controller operates at a frequency of 450kHz. A nominal working status is achieved when the input voltage is set to 25V. There should be 25mA current exceeding 25mA supplied to the controller.
