UC3842DTR Overview
It comes in the 14-SOIC (0.154, 3.90mm Width) package, which makes switching controller suitable for most applications. For 1 outputs, the dc motor controller is appropriate. An enclosure of Tape & Reel (TR) is used to package the PMIC. Transistor Driver dc switching's outputs (s) can be handled by it. dc control's supply and operating voltages are 12V~28V. Qualified to work in an dc switcher with 0°C~70°C TA. This switching controller can switch at Up to 500kHz. dc dc regulator can be generalized using Surface Mount. The dcdc regulator features Frequency Control for efficient switching control. Switch converters are connected to ICs with SWITCHING CONTROLLER analog outputs. There are a DUAL terminal on the switching converters. Various 14 terminations. Some of the control techniques adapted by these dc dc converter ics include PULSE WIDTH MODULATION. It is inputted with a DC switcher's voltage of 15V. Searching "UC3842" will return other relevant dc to dc converter ics. There are 14 pins on switching converter. In particular, switching converter is a type of Switching Regulator or Controllers. According to the test statistics, DC regulator outputs 13.5V voltage. normally, the dc dc regulator's output current is 200mA, which you should keep in mind when starting a project. Voltage regulator dc to dc is designed to operate at 100 % duty cycle during power-ups and power-downs to ensure reliability. Switching controllers operate at 450kHz frequencies. A nominal working status is achieved when the input voltage is set to 25V. It is not recommended to supply more current to the controller than 25mA.
