UC3845BVDG Overview
With a 14-SOIC (0.154, 3.90mm Width) package, the switching controller is suitable for a wide range of applications. For outputs of 1, this dc motor controller is suitable. Packaging for the pmic consists of Tube solid enclosures. A total of Transistor Driver dc switching's outputs can be handled by it. dc controls with 7.6V~30V voltage are supplied and operated. Worked in a -40°C~105°C TA dc switcher before. This switching controller can switch at 500kHz. It is suitable for general dc dc regulator when it is set to Surface Mount. Switching control is made easier with the dcdc regulator's Frequency Control. The switch converters are connected to an analog IC with a SWITCHING CONTROLLER output. Switching converters are designed with the terminal (s) at position DUAL . The 14 terminations can be used for a wide range of dc switching. It includes PULSE WIDTH MODULATION as one of the control techniques dc dc converter ic adapts. A DC switcher's nominal voltage of 15V is input. Other relevant dc to dc converter ics will be returned if you search "UC384*B". Switching converter has a total of 14 pins. Specifically, switching converter falls under the Switching Regulator or Controllers category. According to the test statistics, DC regulator outputs 5.1V voltage. This dc to dc regulator accepts only 25V input voltage at most. The dc dc regulator's usual output current is 1A, which should be noted down when you start a project. The duty cycle of the voltage regulator dc to dc can be set to 48 % on power-up or power-down to ensure reliability. As DC switcher has a Surface Mount, it's suitable for most applications and prototype designs. Switching controller operates at a frequency of 275kHz.
