LT8705AMPFE#TRPBF Overview
This switching controller fits most application requirements since it is packaged in a 38-PowerTFSOP (0.173, 4.40mm Width), 31 Leads package. 2 outputs are supported by the dc motor controller. Tape & Reel (TR) solid enclosure protects the pmic. It is capable of handling Transistor Driver dc switching's outputs (s). This dc control operates at 2.8V~80V and has a 2.8V~80V supply voltage. Work well in dc switchers with a -55°C~125°C. This switching controller can switch at 100kHz~400kHz. A generalization of dc dc regulator can be made using Surface Mount. Enable, Frequency Control, Soft Start provides dcdc regulator efficient switching control. The switch converters are connected to a SWITCHING CONTROLLER analog IC. Switching converters are designed with the terminal (s) at position DUAL . The 31 terminations can be used for a wide range of dc switching. DC switcher's input voltageis 12V volts. Search for "LT8705" to find other relevant dc to dc converter ics. There are only 31 pins on switching converter. Considering the dc to dc regulator can only accept 80V input voltage, it is important to take note of this. Tests are conducted at 80V to determine the dc controller's highest voltage output.
