UC3845D8G4 Overview


It comes in a 8-SOIC (0.154, 3.90mm Width) package, so switching controller can be used for most applications. 1 outputs are supported by the dc motor controller. PMIC packaging is solid with a Tube enclosure. With this function, you can deal with Transistor Driver dc switching's outputs (s). The supply and operating voltage of the dc control are 12V~28V. A 0°C~70°C TA dc switcher is not a problem. This switching controller can switch at 500kHz. The Surface Mount value makes it suitable for general dc dc regulator. DCDC regulator is controlled efficiently by Frequency Control. A SWITCHING CONTROLLER analog IC is connected to the switch converters. The switching converters's terminals (s) are designed at DUAL. Various 8 terminations. It includes PULSE WIDTH MODULATION as one of the control techniques dc dc converter ic adapts. 15V nominal DC switcher's voltage input. UC3845 can be used to locate other relevant dc to dc converter ics. 8 pins are on switching converter. Specifically, switching converter falls under the Switching Regulator or Controllers category. As determined by the test statistics, the output voltage of DC regulator is 5V. If you are starting a new project, you should note the dc dc regulator's typical output current is 200mA. To ensure the reliability under power-up and power-down, the maximum duty cycle of the voltage regulator dc to dc is set as 50 %. Switching controller operates at 450kHz Hz. It is possible to set the input voltage to 25V for nominal working status. 25mA more than 25mA current should be supplied to the controller. If there is 11mA current flow input, then the switching converter could operate.
