UC3845AD8G4 Overview


It comes in a 8-SOIC (0.154, 3.90mm Width) package, so switching controller can be used for most applications. dc motor controller is suitable for 1 output generation. Tube solid enclosure protects the pmic. It is capable of dealing with Transistor Driver dc switching's output (s). dc switching's7.6V~30V is the supply voltage and the operating voltage of the dc control. Worked in a 0°C~70°C TA dc switcher before. Switching can be done at 500kHz with this switching controller. It is suitable for general dc dc regulator when it is set to Surface Mount. For efficient switching control, the dcdc regulator features Frequency Control. Switch converters are connected to ICs with SWITCHING CONTROLLER analog outputs. The switching converters's terminals (s) are designed at DUAL. Different dc switching's functions can be applied to 8 terminations. This dc dc converter ic uses a variety of control techniques, including PULSE WIDTH MODULATION. There is a DC switcher's nominal voltage of 15V. You can find other relevant dc to dc converter ics by searching "UC3845". 8 pins are on switching converter. Switching converter is a type of Switching Regulator or Controllers in particular. DC regulator outputs 15V voltage according to the test statistics. You should note down the dc dc regulator's usual output current of 200mA when you start a project. voltage regulator dc to dcs with a 50 % duty cycle are designed to be reliable when powered on and powered off. Switching controller operates at 450kHz Hz. It is possible to set the input voltage as 25V for nominal working statuses. Switching controller is necessary to provide a voltage of 11V. In order to ensure proper operation, the controller should not receive more current than 25mA.
