UC3825N Overview


Capsuled in the 16-DIP (0.300, 7.62mm) package, the switching controller suits most application needs. For outputs of 2, this dc motor controller is suitable. PMIC packaging is solid with a Tube enclosure. A total of Transistor Driver dc switching's outputs can be handled by it. dc control's supply and operating voltages are 8.4V~30V. Worked in a 0°C~70°C TA dc switcher before. In this switching controller, the switch can be set to 340kHz~460kHz. dc dc regulator can be generalized using Through Hole. In order to control switching efficiently, the dcdc regulator features Current Limit, Enable, Frequency Control, Ramp, Soft Start. A SWITCHING CONTROLLER analog IC is connected to the switch converters. There are a terminal (s) on the switching converters that are designed at DUAL. Various 16 terminations. It includes PULSE WIDTH MODULATION as one of the control techniques dc dc converter ic adapts. 15V nominal DC switcher's voltage input. You can find other relevant dc to dc converter ics by searching "UC3825". The switching converter has a total of 16 pins. Particularly, switching converter is a type of Switching Regulator or Controllers. A 5.1V voltage of DC regulator was detected in the test statistics. If you start a project, note down the dc dc regulator's usual output current of 1.5A. The maximum duty cycle of this voltage regulator dc to dc is set to 85 % to ensure reliability during power-up and power-down. Switching controller operates at 1MHz Hz. For better satisfaction, the value of DC to DC voltage regulator is CAN ALSO BE CONFIGURED IN CURRENT MODE. For nominal working status, the input voltage can be set as 15V. Voltage 15V must be supplied. There should be 33mA more than 33mA amps of current supplied to the controller. If there is 22mA current flow input, then the switching converter could operate.
