LTC3873EDDB#TRM Overview
This switching controller fits most application requirements since it is packaged in a 8-WFDFN Exposed Pad package. It is sufficient to generate 1 outputs with this dc motor controller. Packaged in solid enclosures, this pmic has a Tape & Reel (TR) rating. A total of Transistor Driver dc switching's outputs can be handled by it. dc controls with 8.4V~60V voltage are supplied and operated. Qualified to work in a -40°C~85°C TJ dc switcher. In this switching controller, the switch can be set to 200kHz. A generalization of dc dc regulator can be made using Surface Mount. Switching control is made easier with the dcdc regulator's Current Limit, Enable, Soft Start. A SWITCHING CONTROLLER analog integrated circuit is connected to the switch converters. switching converters terminal (s) are designed to be at DUAL. An array of 8 terminations of dc switching. These dc dc converter ics adapt a variety of control techniques, including PULSE WIDTH MODULATION. The nominal DC switcher's voltage input is 9V. You can find other relevant dc to dc converter ics by searching "LTC3873". This dc dc voltage regulator should be powered by a voltage of 4.4V. At most, the dc to dc regulator accepts 9.5V input voltage.
