UC3843BVDR2 Overview
It comes in the 14-SOIC (0.154, 3.90mm Width) package, which makes switching controller suitable for most applications. 1 outputs are supported by the dc motor controller. Packaged in solid enclosures, this pmic has a Tape & Reel (TR) rating. The program can handle Transistor Driver dc switching's outputs (s). The supply and operating voltage of the dc control are 7.6V~30V. Work well in dc switchers with a -40°C~105°C TA. With this switching controller, you can switch at Up to 500kHz. The Surface Mount allows it to be used for dc dc regulator in general. Frequency Control is used for efficient switching control in the dcdc regulator. A SWITCHING CONTROLLER analog IC is connected to the switch converters. DUAL are the position of the terminal of the switching converters. A variety of 14 terminations are available in dc switching. A few of the control techniques these dc dc converter ics adapt include PULSE WIDTH MODULATION. It is inputted with a DC switcher's voltage of 15V. Searching "UC384*B" will return other relevant dc to dc converter ics. 14 pins are on switching converter. Switching converter is a special type of Switching Regulator or Controllers. According to the test statistics, DC regulator outputs 5.1V voltage. At most, the dc to dc regulator accepts 25V input voltage. normally, the dc dc regulator's output current is 1A, which you should keep in mind when starting a project. The maximum duty cycle of this voltage regulator dc to dc is set to 96 % to ensure reliability during power-up and power-down. Switching controllers operate at 60kHz frequencies. In order to run the voltage regulator dc to dc safely and reliably, users are advised to apply 30V. Dormant dc switchings use 12mA.
