UC3843BD1G Product Details

UC3843BD1G Overview


In the 8-SOIC (0.154, 3.90mm Width) package, the switching controller meets most application requirements. There is sufficient capacity to generate switching controller for outputs 1. There is a Tube solid enclosure around the pmic. With this function, you can deal with Transistor Driver dc switching's outputs (s). DC control operates at 7.6V~30V volts and has 7.6V~30V supply voltage. Suitable for working in an dc switcher that has a 0°C~70°C TA. It can switch at Up to 500kHz. As it has a Surface Mount value, it can be used for general dc dc regulator. To provide efficient switching control, Frequency Control is included in the dcdc regulator. A SWITCHING CONTROLLER analog integrated circuit is connected to the switch converters. DUAL are the position of the terminal of the switching converters. Various 8 terminations. This dc dc converter ic uses a variety of control techniques, including PULSE WIDTH MODULATION. There is a DC switcher's nominal voltage of 15V. In addition to "UC384*B", there are other relevant dc to dc converter ics you can find. There are 8 pins on switching converter. Specifically, switching converter falls under the Switching Regulator or Controllers category. DC regulator outputs 13.4V voltage based on test statistics. The dc to dc regulator can only accept 25V input voltage. A starting point for a project is to note down the dc dc regulator's usual output current, which is 200mA. Voltage regulator dc to dc is designed to operate at 96 % duty cycle during power-ups and power-downs to ensure reliability. Because of DC switcher's Surface Mount, it is suitable for most prototype designs and applications. A frequency of 52kHz is set for the switching controller. Components may become damaged if their current exceeds 17mA.
