UC2842D8 Overview
With its 8-SOIC (0.154, 3.90mm Width) package, the switching controller fits the needs of most applications. The dc motor controller is adquate to generate for 1 outputs. Packaging for the pmic consists of Tube solid enclosures. There are Transistor Driver dc switching's output (s) that it can handle. A 12V~28V voltage is supplied to the dc control and used for operating it. Work well in dc switchers with a -40°C~85°C TA. There is a switch at Up to 500kHz that can be used with this controller. The Surface Mount value makes it suitable for general dc dc regulator. Frequency Control is used for efficient switching control in the dcdc regulator. A SWITCHING CONTROLLER analog integrated circuit is connected to the switch converters. DUAL are the position of the terminal of the switching converters. The 8 terminations can be used for a wide range of dc switching. Some of the control techniques used by these dc dc converter ics are PULSE WIDTH MODULATION. There is a DC switcher's nominal voltage of 15V. UC2842 can be used to locate other relevant dc to dc converter ics. There are 8 pins on switching converter. Switching converter is a type of Switching Regulator or Controllers in particular. A 13.5V voltage of DC regulator was detected in the test statistics. It's important to remember that the dc dc regulator's normaloutput current is 200mA, so you should note it down when starting a new project. The maximum duty cycle of this voltage regulator dc to dc is set to 100 % to ensure reliability during power-up and power-down. There is 450kHz frequency setting on the switching controller. You can set the input voltage to 25V for nominal working status. The controller should not be supplied with more current than 25mA.
