LT8705EUHF#PBF Overview

The switching controller fits in the 38-WFQFN Exposed Pad package and is ideal for most applications. There is sufficient capacity to generate switching controller for outputs 2. Packaging for the pmic consists of Tube solid enclosures. It is capable of dealing with Transistor Driver dc switching's output (s). dc switching'sdc control's supply and operating voltages are 2.8V~80V. Worked in an dc switcher with a -40°C~125°C TJ rating. Using this switching controller, it is possible to switch at 100kHz~400kHz. dc dc regulators can be carried out with Surface Mount. Enable, Frequency Control, Soft Start is used for efficient switching control in the dcdc regulator. An analog IC with the SWITCHING CONTROLLER signal is connected to the switch converters. The switching converters's terminals (s) are designed at QUAD. A variety of terminations with 38 of dc switching. It includes PULSE WIDTH MODULATION as one of the control techniques dc dc converter ic adapts. 12V nominal DC switcher's voltage input. You can find other relevant dc to dc converter ics by searching "LT8705". Specially, switching converter corresponds to type Switching Regulator or Controllers. As determined by the test statistics, the output voltage of DC regulator is 6.35V. The dc to dc regulator is limited to 80V input voltage. For better satisfaction, the value of DC to DC voltage regulator is ALSO OPERATES IN ADJUSTABLE MODE FROM 1.3V TO 80V.
