UC2842D8G4 Overview
It comes in a 14-SOIC (0.154, 3.90mm Width) package, so switching controller can be used for most applications. There is enough capacity in the dc motor controller to generate the output for the 1 input. Tube is the solid enclosure in which PMIC is packaged. There are Transistor Driver dc switching's output (s) that it can handle. This dc control has a supply voltage and operating voltage of 12V~28V. Workable in an dc switcher where -40°C~85°C TA is the -40°C~85°C TArm. With this switching controller, you can switch at Up to 500kHz. The Surface Mount allows it to be used for dc dc regulator in general. To provide efficient switching control, Frequency Control is included in the dcdc regulator. Switch converters are connected to ICs with SWITCHING CONTROLLER analog outputs. Terminal (s) of the switching converters are designed at the DUAL position. 8 terminations with various dc switching's functions. Some of the control techniques used by these dc dc converter ics are PULSE WIDTH MODULATION. DC switcher's voltage input is 15V. Other relevant dc to dc converter ics can be found by searching "UC2842". 8 pins are on switching converter. In particular, switching converter is a type of Switching Regulator or Controllers. Statistically, the DC regulator outputs 13.5V voltage. In most cases, the dc dc regulator's output current is 200mA. This information should be noted when you begin working with the component. 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. Switching controllers work at 450kHz Hz. Input voltage can be set to 25V for nominal working status. In order to ensure proper operation, the controller should not receive more current than 25mA.
