LT8705AHFE Overview


The switching controller fits in the 38-PowerTFSOP (0.173, 4.40mm Width), 31 Leads package and is ideal for most applications. 2 outputs are supported by the dc motor controller. 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. A -40°C~150°C dc switcher is not a problem. The switching controller is capable of switching at the 100kHz~400kHz position. The Surface Mount allows it to be used for dc dc regulator in general. The dcdc regulator features Enable, Frequency Control, Soft Start for efficient switching control. An analog IC with the SWITCHING CONTROLLER signal is connected to the switch converters. The switching converters's terminals (s) are designed at DUAL. 31 terminations with various dc switching's functions. The nominal DC switcher's voltage input is 12V. It should be fully noted that the dc to dc regulator only accepts 80V input voltage at most. It is tested at 80V to determine what the dc controller's highest voltage output is.
