UC3874DW-2 Overview
As a result of 18-SOIC (0.295, 7.50mm Width) compact design, the switching controller is compatible with most applications. dc motor controller is suitable for 1 output generation. Packaged in solid enclosures, this pmic has a Tube rating. A total of Transistor Driver dc switching's outputs can be handled by it. The supply and operating voltage of the dc control are 4.4V~36V. Suitable for work in a 0°C~70°C TA dc switcher. Using this switching controller, it is possible to switch at Up to 300kHz. dc dc regulator is made easier with Surface Mount. To ensure efficient switching, this dcdc regulator features a Soft Start. The switch converters are connected to an analog IC with a SWITCHING CONTROLLER output. There are a DUAL terminal on the switching converters. A variety of 18 terminations are available in dc switching. These dc dc converter ics adapt several control methods, including PULSE WIDTH MODULATION. A DC switcher's nominal voltage of 12V is input. UC3874 can be used to locate other relevant dc to dc converter ics. Total pins of switching converter are 18. In particular, switching converter belongs to the Switching Regulator or Controllers family. In most applications and prototype designs, DC switcher is qualified as a Surface Mount. DC regulator's maximum frequency is 300kHz. When running the voltage regulator dc to dc in a circuit, users should apply 36V to ensure safety and reliability. Current is output to the greatest value of 1A.
