UC3843ADG4 Overview
This switching controller fits most application requirements since it is packaged in a 14-SOIC (0.154, 3.90mm Width) package. It is sufficient to generate 1 outputs with this dc motor controller. There is a Tube solid enclosure around the pmic. It is capable of handling Transistor Driver dc switching's outputs (s). The supply and operating voltage of the dc control are 7.6V~30V. Workable in an dc switcher where 0°C~70°C TA is the 0°C~70°C TArm. With this switching controller, you can switch at Up to 500kHz. Surface Mount makes it suitable for general dc dc regulator. To provide efficient switching control, Frequency Control is included in the dcdc regulator. Thare switch converters are connected to an analog integrated circuit (IC) of type SWITCHING CONTROLLER. A switching converters's terminal (s) sits at the DUAL position. There are many different types of terminations for 14. This dc dc converter ic uses a variety of control techniques, including PULSE WIDTH MODULATION. The DC switcher's nominal voltage is 15V. In addition to "UC3843", there are other relevant dc to dc converter ics you can find. In total, switching converter has 14 pins. In particular, switching converter is a type of Switching Regulator or Controllers. Test statistics indicate DC regulator outputs 5.1V voltage. normally, the dc dc regulator's output current is 200mA, which you should keep in mind when starting a project. To ensure the reliability under power-up and power-down, the maximum duty cycle of the voltage regulator dc to dc is set as 100 %. Switching controllers work at 500kHz Hz. A nominal working status is achieved when the input voltage is set to 25V. Switching controller is necessary to provide a voltage of 11V. There should be 25mA current exceeding 25mA supplied to the controller. An input of 11mA current flow could satisfy the operation of the switching converter .
