UC3845BVN Overview


This switching controller fits most application requirements since it is packaged in a 8-DIP (0.300, 7.62mm) package. For 1 outputs, the dc motor controller is appropriate. An enclosure of Tube is used to package the PMIC. A total of Transistor Driver dc switching's outputs can be handled by it. dc control's supply and operating voltages are 7.6V~30V. Suitable for a -40°C~105°C TA dc switcher. With this switching controller, you can switch at 500kHz. The Through Hole value makes it suitable for general dc dc regulator. Frequency Control is used for efficient switching control in the dcdc regulator. An analog IC with the SWITCHING CONTROLLER signal is connected to the switch converters. The switching converters's terminal (s) are designed at DUAL . An array of 8 terminations of dc switching. PULSE WIDTH MODULATION is an example of one of the control techniques these dc dc converter ics adapt. It is inputted with a DC switcher's voltage of 15V. Search for "UC384*B" to find other relevant dc to dc converter ics. Switching converter has a total of 8 pins. Switching converter is a type of Switching Regulator or Controllers in particular. Based on the test statistics, DC regulator outputs voltage 5.1V. It should be fully noted that the dc to dc regulator only accepts 25V input voltage at most. In most cases, the dc dc regulator's output current is 1A. This information should be noted when you begin working with the component. It is set to 48 % duty cycle to ensure voltage regulator dc to dc reliability during power-ups and power-downs. The switching controller works at a frequency of 275kHz. A circuit should contain 30V in order to ensure the voltage regulator dc to dc runs safely and reliably. In a dormant state, the dc switching uses 12mA.
