LT8705AIUHF Overview
Capsuled in the 38-WFQFN Exposed Pad package, the switching controller can be used for a wide range of applications. For outputs of 2, this dc motor controller is suitable. It is capable of handling Transistor Driver dc switching's outputs (s). Voltages 2.8V~80V are the dc control's supply voltage and operating voltage, respectively. Suitable for work in a -40°C~125°C dc switcher. It can switch at 100kHz~400kHz. The Surface Mount value makes it suitable for general dc dc regulator. DCDC regulator is controlled efficiently by Enable, Frequency Control, Soft Start. The switch converters are connected to an analog IC with a SWITCHING CONTROLLER output. There are a terminal (s) on the switching converters that are designed at QUAD. A variety of 38 terminations are available in dc switching. The nominal DC switcher's voltage input is 12V. It should be noted that the dc to dc regulator only accepts 80V voltage as input voltage. In order to satisfy the need, DC to DC voltage regulator has a value of SEATED HT-CALCULATED. Tests are conducted at 80V to determine the dc controller's highest voltage output.
