UC3842AD Overview


This switching controller fits most application requirements since it is packaged in a 8-SOIC (0.154, 3.90mm Width) package. For 1 outputs, the dc motor controller is appropriate. Packaged in solid enclosures, this pmic has a Tube rating. The system can process Transistor Driver dc switching's outputs (s). 10V~30V is the supply voltage and the operating voltage of the dc control. Worked in a 0°C~70°C TA dc switcher before. Using this switching controller, it is possible to switch at Up to 500kHz. dc dc regulators can be carried out with Surface Mount. In order to control switching efficiently, the dcdc regulator features Frequency Control. Thare switch converters are connected to an analog integrated circuit (IC) of type SWITCHING CONTROLLER. There are a terminal (s) on the switching converters that are designed at DUAL. A variety of 14 terminations are available in dc switching. The control methods that these dc dc converter ics use include PULSE WIDTH MODULATION. DC switcher's voltage input is 15V. Searching "UC3842" will return other relevant dc to dc converter ics. The switching converter has a total of 8 pins. In particular, switching converter is a type of Switching Regulator or Controllers. Based on the test statistics, DC regulator outputs voltage 5.1V. It should be noted that the dc to dc regulator only accepts 30V voltage as input voltage. If you are starting a new project, you should note the dc dc regulator's typical output current is 1A. During power-up and power-down, the maximum duty cycle of the voltage regulator dc to dc is set to 100 %. As DC switcher has a Surface Mount, it's suitable for most applications and prototype designs. The supply current is 17mA. This the controllers dc receives a 17mA nominal current supply.
