LTC3873EDDB-5#TRMPBF Overview
With its 8-WFDFN Exposed Pad package, the switching controller fits the needs of most applications. This dc motor controller can be used to generate outputs with 1 numbers. PMIC is packaged in a solid enclosure of Tape & Reel (TR). Transistor Driver dc switching's outputs (s) can be handled by it. dc controls with 4.1V~60V voltage are supplied and operated. Suitable for a -40°C~85°C TA dc switcher. A generalization of dc dc regulator can be made using Surface Mount. For efficient switching control, the dcdc regulator features Current Limit, Enable, Soft Start. SWITCHING CONTROLLER analog IC connects the switch converters. Switching converters are designed with the terminal (s) at position DUAL . A variety of 8 terminations are available in 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 5V. LTC3873 can be used to locate other relevant dc to dc converter ics. Switching converter is a special type of Switching Regulator or Controllers. It is recommended to use 3.5V as the minimum input voltage of dc dc voltage regulator. A maximum voltage of 9V is accepted by the dc to dc regulator as an input voltage. This controller can operate at a frequency up to 240kHz.
