UC3825AQ Overview


With its 20-LCC (J-Lead) package, the switching controller fits the needs of most applications. There is enough capacity in the dc motor controller to generate the output for the 2 input. Tube solid enclosure protects the pmic. With this function, you can deal with Transistor Driver dc switching's outputs (s). Voltages 8.4V~22V are the dc control's supply voltage and operating voltage, respectively. Qualified to work in an dc switcher with 0°C~70°C TA. The switching controller can be switched at 400kHz~1MHz. dc dc regulators can be carried out with Surface Mount. Featured in the dcdc regulator is Current Limit, Frequency Control, Ramp, Soft Start which allows efficient switching control. A SWITCHING CONTROLLER analog integrated circuit is connected to the switch converters. There are a QUAD terminal on the switching converters. 20 terminations with a variety of function. It includes PULSE WIDTH MODULATION as one of the control techniques dc dc converter ic adapts. DC switcher's voltage input is 12V. Searching "UC3825" will return other relevant dc to dc converter ics. In total, switching converter has 20 pins. Switching converter is a special type of Switching Regulator or Controllers. It is recommended that the dc dc voltage regulator's minimum input voltage be 8.8V. Statistically, the DC regulator outputs 2V voltage. It's important to remember that the dc dc regulator's normaloutput current is 200mA, so you should note it down when starting a new project. It is set to 50 % duty cycle to ensure voltage regulator dc to dc reliability during power-ups and power-downs. A frequency of 1MHz is used by the switching controller. The value of DC to DC voltage regulator is set at CAN ALSO BE CONFIGURED IN CURRENT MODE in order to fulfill the requirements more effectively.
