UC2842D8TR Overview
Capsuled in the 8-SOIC (0.154, 3.90mm Width) package, the switching controller suits most application needs. There is sufficient capacity to generate switching controller for outputs 1. Tape & Reel (TR) solid enclosure protects the pmic. Transistor Driver dc switching's outputs (s) can be handled by it. dc controls with 12V~28V voltage are supplied and operated. Suitable for work in a -40°C~85°C TA dc switcher. The switching controller can be switched at Up to 500kHz. As it has a Surface Mount value, it can be used for general dc dc regulator. 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. Thare switching converters has a terminal (s) at DUAL . 8 terminations with various dc switching's functions. It includes PULSE WIDTH MODULATION as one of the control techniques dc dc converter ic adapts. 15V nominal DC switcher's voltage input. In addition to "UC2842", there are other relevant dc to dc converter ics you can find. There are 8 pins on switching converter. In particular, switching converter belongs to the Switching Regulator or Controllers family. Statistically, DC regulator outputs 13.5V volts. A starting point for a project is to note down the dc dc regulator's usual output current, which is 200mA. During power-up and power-down, the maximum duty cycle of the voltage regulator dc to dc is set to 100 %. Switching controllers work at 450kHz Hz. For nominal working status, the input voltage can be set as 25V. Because the dc switcher's maximum input voltage is 25V users must limit the voltage accordingly. There will be 1A current output from the dc switcher above 1A. There should be 25mA current exceeding 25mA supplied to the controller. 11mA current flow input could be used to operate the switching converter .
