LT8705AEFE#PBF Overview


As a result of 38-PowerTFSOP (0.173, 4.40mm Width), 31 Leads compact design, the switching controller is compatible with most applications. For 2 outputs, the dc motor controller is appropriate. The pmic is packaged in Tube solid enclosure. It is capable of dealing with Transistor Driver dc switching's output (s). dc switching'sThe supply and operating voltage of the dc control are 2.8V~80V. Qualified to work in a -40°C~125°C dc switcher. This switching controller can switch at 100kHz~400kHz. dc dc regulator can be generalized using Surface Mount. Featured in the dcdc regulator is Enable, Frequency Control, Soft Start which allows efficient switching control. SWITCHING CONTROLLER analog IC connects the switch converters. The switching converters's terminal (s) are designed at DUAL . A variety of terminations with 31 of dc switching. There is a DC switcher's nominal voltage of 12V. Search for "LT8705" to find other relevant dc to dc converter ics. Considering the dc to dc regulator can only accept 80V input voltage, it is important to take note of this. The dc controller's highest voltage output is tested at 80V.
