UC3843DG4 Overview
This switching controller fits most application requirements since it is packaged in a 14-SOIC (0.154, 3.90mm Width) package. For 1 outputs, the dc motor controller is appropriate. The pmic is packaged in Tube solid enclosure. With this function, you can deal with Transistor Driver dc switching's outputs (s). A 12V~28V voltage is supplied to the dc control and used for operating it. Qualified to work in an dc switcher with 0°C~70°C TA. Switching can be done at Up to 500kHz with this switching controller. The Surface Mount allows it to be used for dc dc regulator in general. The dcdc regulator features Frequency Control for efficient switching control. SWITCHING CONTROLLER analog IC connects the switch converters. The switching converters's terminals (s) are designed at DUAL. The 14 terminations can be used for a wide range of dc switching. A few of the control techniques these dc dc converter ics adapt include PULSE WIDTH MODULATION. 15V nominal DC switcher's voltage input. In addition to "UC3843", there are other relevant dc to dc converter ics you can find. Switching converter has a total of 14 pins. Switching converter is a type of Switching Regulator or Controllers in particular. Statistically, the DC regulator outputs 13.5V voltage. You should note that the dc dc regulator's usual output current is 200mA. Voltage regulator dc to dc is designed to operate at 100 % duty cycle during power-ups and power-downs to ensure reliability. Switching controller operates at 500kHz Hz. It is possible to set the input voltage as 25V for nominal working statuses. In order to ensure the dc switcher's functionality, users must limit the voltage to 25V due to the dc switcher's maximum input voltage. DC switchers cannot produce output currents greater than 1A. 25mA more than 25mA current should be supplied to the controller. The switching converter could be operated with an input of 11mA current flow.
