LT8390IFE Overview
The switching controller fits in the 28-TSSOP (0.173, 4.40mm Width) Exposed Pad package and is ideal for most applications. It is sufficient to generate 1 outputs with this dc motor controller. The program can handle Transistor Driver dc switching's outputs (s). The supply and operating voltage of the dc control are 4V~60V. Suitable for working in an dc switcher that has a -40°C~125°C. The switching controller is capable of switching at the 190kHz~630kHz position. It is suitable for general dc dc regulator when it is set to Surface Mount. To provide efficient switching control, Current Limit, Frequency Control, Soft Start is included in the dcdc regulator. A SWITCHING CONTROLLER analog IC is connected to the switch converters. There are a DUAL terminal on the switching converters. Different dc switching's functions can be applied to 28 terminations. DC switcher's voltage input is 12V. LT8390 can be used to locate other relevant dc to dc converter ics. An input voltage of 4V is the minimum required for the dc dc voltage regulator. A maximum voltage of 60V is accepted by the dc to dc regulator as an input voltage.
