LT8705AEUHF Overview


This switching controller fits most application requirements since it is packaged in a 38-WFQFN Exposed Pad package. This dc motor controller can be used to generate outputs with 2 numbers. With this function, you can deal with Transistor Driver dc switching's outputs (s). A 2.8V~80V voltage is supplied to the dc control and used for operating it. Worked in a -40°C~125°C dc switcher before. There is a switch at 100kHz~400kHz that can be used with this controller. As it has a Surface Mount value, it can be used for general dc dc regulator. Featured in the dcdc regulator is Enable, Frequency Control, Soft Start which allows efficient switching control. The switch converters are connected to a SWITCHING CONTROLLER analog IC. switching converters terminal (s) are designed to be at QUAD. The 38 terminations can be used for a wide range of dc switching. There is a DC switcher's nominal voltage of 12V. The dc to dc regulator can only accept a maximum input voltage of 80V. The value of DC to DC voltage regulator is set at SEATED HT-CALCULATED in order to fulfill the requirements more effectively. The dc controller's highest voltage output is tested at 80V.
