TL2843BD Overview


With a 14-SOIC (0.154, 3.90mm Width) package, the switching controller is suitable for a wide range of applications. There is sufficient capacity to generate switching controller for outputs 1. There is a Tube solid enclosure around the pmic. There are Transistor Driver dc switching's output (s) that it can handle. dc control's supply and operating voltages are 7.6V~30V. Suitable for working in an dc switcher that has a -40°C~85°C TA. This switching controller can switch at Up to 500kHz. The Surface Mount value makes it suitable for general dc dc regulator. To provide efficient switching control, Frequency Control is included in the dcdc regulator. An analog IC SWITCHING CONTROLLER is connected to the switch converters. Thare switching converters has a terminal (s) at DUAL . 14 terminations with a variety of function. PULSE WIDTH MODULATION is an example of one of the control techniques these dc dc converter ics adapt. DC switcher's input voltageis set to 15V. Other relevant dc to dc converter ics can be found by searching "TL2843". The switching converter has a total of 14 pins. Switching converter type is specifically Switching Regulator or Controllers. A 30V voltage of DC regulator was detected in the test statistics. The dc dc regulator's usual output current is 200mA, which should be noted down when you start a project. During power-up and power-down, the maximum duty cycle of the voltage regulator dc to dc is set to 100 %. A frequency of 500kHz is set for the switching controller. It is possible to set the input voltage as 5.5V for nominal working statuses. Switching controller is necessary to supply a voltage of 15V. You should not supply more current than 30mA to the controller.
