UC2842AD Overview
With its 14-SOIC (0.154, 3.90mm Width) package, the switching controller fits the needs of most applications. It is sufficient to generate 1 outputs with this dc motor controller. With this function, you can deal with Transistor Driver dc switching's outputs (s). 10V~30V is the operating voltage and supply voltage of the dc control. Suitable for working in an dc switcher that has a -40°C~85°C TA. With this switching controller, you can switch at Up to 500kHz. It is suitable for general dc dc regulator when it is set to Surface Mount. To ensure efficient switching, this dcdc regulator features a Frequency Control. Thare switch converters are connected to an analog integrated circuit (IC) of type SWITCHING CONTROLLER. DUAL are the position of the terminal of the switching converters. A variety of 14 terminations are available in dc switching. A few of the control techniques these dc dc converter ics adapt include PULSE WIDTH MODULATION. The DC switcher's nominal voltage is 15V. Searching "UC*84" will return other relevant dc to dc converter ics. Switching converter has a total of 14 pins. Switching converter type is specifically Switching Regulator or Controllers. Test statistics indicate DC regulator outputs 13.5V voltage. The dc to dc regulator can only accept a maximum input voltage of 30V. If you are starting a new project, you should note the dc dc regulator's typical output current is 200mA. As a result of this, the maximum duty cycle of the voltage regulator dc to dc must remain 100 % during power-up and power-down. As DC switcher has a Surface Mount, it's suitable for most applications and prototype designs. Switching controller operates at a frequency of 500kHz.
