UC3843BVD1 Overview


This switching controller fits most application requirements since it is packaged in a 8-SOIC (0.154, 3.90mm Width) package. For 1 outputs, the dc motor controller is appropriate. Packaged in solid enclosures, this pmic has a Tube rating. It is capable of dealing with Transistor Driver dc switching's output (s). dc switching'sThis dc control operates at 7.6V~30V and has a 7.6V~30V supply voltage. Suitable for work in a -40°C~105°C TA dc switcher. With this switching controller, you can switch at Up to 500kHz. The Surface Mount value makes it suitable for general dc dc regulator. Frequency Control is used for efficient switching control in the dcdc regulator. A SWITCHING CONTROLLER analog integrated circuit is connected to the switch converters. The switching converters's terminals (s) are designed at DUAL. Different dc switching's functions can be applied to 8 terminations. To name a few of the control techniques these dc dc converter ics adapt, it includes PULSE WIDTH MODULATION. DC switcher's voltage input of 15V. In addition to "UC384*B", there are other relevant dc to dc converter ics you can find. There are only 8 pins on switching converter. There is a particular type of Switching Regulator or Controllers in switching converter. Test statistics indicate DC regulator outputs 5.1V voltage. At most, the dc to dc regulator accepts 25V input voltage. If you start a project, note down the dc dc regulator's usual output current of 1A. It is set to 96 % duty cycle to ensure voltage regulator dc to dc reliability during power-ups and power-downs. 275kHz is the maximum frequency of this dc regulators. In order for the voltage regulator dc to dc to perform safely and reliably in a circuit, users are advised to apply 30V.
