LT8390IUFD#PBF Overview


It comes in the 28-WFQFN Exposed Pad package, which makes switching controller suitable for most applications. There is enough capacity in the dc motor controller to generate the output for the 1 input. Tube is the solid enclosure in which PMIC is packaged. With this function, you can deal with Transistor Driver dc switching's outputs (s). 4V~60V is the supply voltage and the operating voltage of the dc control. Work well in dc switchers with a -40°C~125°C TJ. This switching controller can switch at 190kHz~630kHz. dc dc regulator is made easier with Surface Mount. To provide efficient switching control, Current Limit, Frequency Control, Soft Start is included in the dcdc regulator. A SWITCHING CONTROLLER analog integrated circuit is connected to the switch converters. There are a QUAD terminal on the switching converters. 28 terminations with a variety of function. It is inputted with a DC switcher's voltage of 12V. A search for "LT8390" will reveal other relevant dc to dc converter ics. An input voltage of 4V is the minimum required for the dc dc voltage regulator. The dc to dc regulator is limited to 60V input voltage.
