LTC3731HUH#TRPBF Overview

Capsuled in the 32-WFQFN Exposed Pad package, the switching controller suits most application needs. dc motor controller is suitable for 3 output generation. PMIC packaging is solid with a Tape & Reel (TR) enclosure. Transistor Driver dc switching's outputs (s) can be handled by it. 3.8V~7V is the supply voltage and the operating voltage of the dc control. Suitable for working in an dc switcher that has a -40°C~140°C TJ. There is a switch at 225kHz~680kHz that can be used with this controller. It is suitable for general dc dc regulator when it is set to Surface Mount. To ensure efficient switching, this dcdc regulator features a Enable, Phase Control, Power Good, Soft Start. A SWITCHING CONTROLLER analog IC is connected to the switch converters. QUAD are the position of the terminal of the switching converters. The 32 terminations can be used for a wide range of dc switching. This dc dc converter ic uses a variety of control techniques, including PULSE WIDTH MODULATION. The DC switcher's nominal voltage is 5V. You can find other relevant dc to dc converter ics by searching "LTC3731". Total pins of switching converter are 32. Switching converter is a type of Switching Regulator or Controllers in particular. The dc to dc regulator can only accept a maximum input voltage of 7V. DC regulator's maximum frequency is 750kHz. The output of this function is the greatest value of 5A. Thare are switch converters of the PolyPhase? series. Communication with high quality requires 1 channels.
