LT8705IUHF#PBF Overview

The switching controller fits in the 38-WFQFN Exposed Pad package and is ideal for most applications. There is enough capacity in the dc motor controller to generate the output for the 2 input. Packaged in solid enclosures, this pmic has a Tube rating. Transistor Driver dc switching's outputs (s) can be handled by it. The supply and operating voltage of the dc control are 2.8V~80V. Suitable for a -40°C~125°C TJ dc switcher. With this switching controller, you can switch at 100kHz~400kHz. The Surface Mount makes it ideal for general dc dc regulator. In order to control switching efficiently, the dcdc regulator features Enable, Frequency Control, Soft Start. A SWITCHING CONTROLLER analog integrated circuit is connected to the switch converters. There are a terminal (s) on the switching converters that are designed at QUAD. The 38 terminations can be used for a wide range of dc switching. The control methods that these dc dc converter ics use include PULSE WIDTH MODULATION. A DC switcher's nominal voltage of 12V is input. A search for "LT8705" will reveal other relevant dc to dc converter ics. Specifically, switching converter falls under the Switching Regulator or Controllers category. DC regulator outputs 6.35V voltage based on test statistics. Considering the dc to dc regulator can only accept 80V input voltage, it is important to take note of this. In order to satisfy the need, DC to DC voltage regulator has a value of ALSO OPERATES IN ADJUSTABLE MODE FROM 1.3V TO 80V.
