UC3843BDG Overview


As a result of 14-SOIC (0.154, 3.90mm Width) compact design, the switching controller is compatible with most applications. 1 outputs can be generated with the dc motor controller. PMIC is packaged in a solid enclosure of Tube. The program can handle Transistor Driver dc switching's outputs (s). Voltages 7.6V~30V are the dc control's supply voltage and operating voltage, respectively. Suitable for working in an dc switcher that has a 0°C~70°C TA. It can switch at Up to 500kHz. Surface Mount makes it suitable for general dc dc regulator. To ensure efficient switching, this dcdc regulator features a Frequency Control. An analog IC SWITCHING CONTROLLER is connected to the switch converters. 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. There is a DC switcher's nominal voltage of 15V. You can find other relevant dc to dc converter ics by searching "UC384*B". There are a total of 14 pins on switching converter. Specifically, switching converter falls under the Switching Regulator or Controllers category. Statistically, the DC regulator outputs 13.4V voltage. The dc to dc regulator is limited to 25V input voltage. You should note that the dc dc regulator's usual output current is 200mA. To ensure the reliability under power-up and power-down, the maximum duty cycle of the voltage regulator dc to dc is set as 96 %. DC switcher's Surface Mount makes it qualified for most application and prototype designs. DC switcher'sSwitching controller operates at a frequency of 250kHz.
