LT8705AEUHF Overview

In the 38-WFQFN Exposed Pad package, the switching controller meets most application requirements. There is sufficient capacity to generate switching controller for outputs 2. With this function, you can deal with Transistor Driver dc switching's outputs (s). DC control operates at 2.8V~80V volts and has 2.8V~80V supply voltage. Suitable for working in an dc switcher that has a -40°C~125°C. It can switch at 100kHz~400kHz. As it has a Surface Mount value, it can be used for general dc dc regulator. To provide efficient switching control, Enable, Frequency Control, Soft Start is included in the dcdc regulator. A SWITCHING CONTROLLER analog integrated circuit is connected to the switch converters. QUAD are the position of the terminal of the switching converters. Various 38 terminations. There is a DC switcher's nominal voltage of 12V. The dc to dc regulator can only accept 80V input voltage. Hence, SEATED HT-CALCULATED is used to better suit the DC to DC voltage regulator's situation. We test the dc controller's highest voltage output at 80V.
