UC3843BD Overview
In the 14-SOIC (0.154, 3.90mm Width) package, the switching controller meets most application requirements. This dc motor controller can be used to generate outputs with 1 numbers. Packaging for the pmic consists of Tube solid enclosures. It is capable of handling Transistor Driver dc switching's outputs (s). DC control operates at 7.6V~30V volts and has 7.6V~30V supply voltage. A 0°C~70°C TA dc switcher is not a problem. This switching controller can switch at Up to 500kHz. As it has a Surface Mount value, it can be used for general dc dc regulator. Switching control is made easier with the dcdc regulator's Frequency Control. SWITCHING CONTROLLER analog IC connects the switch converters. DUAL are the position of the terminal of the switching converters. 14 terminations with a variety of function. These dc dc converter ics adapt several control methods, including PULSE WIDTH MODULATION. DC switcher's voltage input is 15V. UC384*B can be searched for other relevant dc to dc converter ics. Pins number 14 of switching converter in total. In particular, switching converter belongs to the Switching Regulator or Controllers family. As determined by the test statistics, the output voltage of DC regulator is 5.1V. It should be fully noted that the dc to dc regulator only accepts 25V input voltage at most. If you start a project, note down the dc dc regulator's usual output current of 1A. Voltage regulator dc to dc is designed to operate at 96 % duty cycle during power-ups and power-downs to ensure reliability. Switching controllers operate at 60kHz frequencies. A circuit should contain 30V in order to ensure the voltage regulator dc to dc runs safely and reliably. During dormancy, the dc switching uses 12mA.
