UC3842D8TR Product Details

UC3842D8TR Overview


In the 8-SOIC (0.154, 3.90mm Width) package, the switching controller meets most application requirements. dc motor controller is suitable for 1 output generation. Packaged in solid enclosures, this pmic has a Tape & Reel (TR) rating. It is capable of handling Transistor Driver dc switching's outputs (s). A 12V~28V voltage is supplied to the dc control and used for operating it. Suitable for working in an dc switcher that has a 0°C~70°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 . A variety of dc switching's functions can be performed on 8 terminations. The control methods that these dc dc converter ics use include PULSE WIDTH MODULATION. The DC switcher's nominal voltage is 15V. You can find other relevant dc to dc converter ics by searching "UC3842". Pins number 8 of switching converter in total. Switching converter is a special type of Switching Regulator or Controllers. As determined by the test statistics, the output voltage of DC regulator is 13.5V. If you start a project, note down the dc dc regulator's usual output current of 200mA. Power-up and power-down reliability is ensured voltage regulator dc to dc by setting the maximum duty cycle to 100 %. Switching controllers work at 450kHz Hz. For nominal working status, the input voltage can be set as 25V. It is important that the controller is supplied with 25mA more than 25mA volts of current.
