LTC3731IUH#TRPBF Product Details
LTC3731IUH#TRPBF Overview
It comes in the 32-WFQFN Exposed Pad package, which makes switching controller suitable for most applications. It is sufficient to generate 3 outputs with this dc motor controller. Packaging for the pmic consists of Tape & Reel (TR) solid enclosures. The program can handle Transistor Driver dc switching's outputs (s). dc control's supply and operating voltages are 3.8V~7V. Qualified to work in an dc switcher with -40°C~85°C TA. The switching controller can be switched at 225kHz~680kHz. dc dc regulators can be carried out with Surface Mount. Enable, Phase Control, Power Good, Soft Start provides dcdc regulator efficient switching control. The switch converters are connected to an analog IC with a SWITCHING CONTROLLER output. There are a QUAD terminal on the switching converters. Different dc switching's functions can be applied to 32 terminations. Some of the control techniques adapted by these dc dc converter ics include PULSE WIDTH MODULATION. DC switcher's voltage input of 5V. LTC3731 can be searched for other relevant dc to dc converter ics. In total, switching converter has 32 pins. Switching converter type is specifically Switching Regulator or Controllers. This dc dc voltage regulator should be powered by a voltage of 4.5V. 750kHz is the maximum frequency of this dc regulators. 5A is the greatest value switching converter outputs as current. A dc to dc voltage regulator in the PolyPhase® series, it belongs to this family. In order to ensure high-quality communication, there are 1 channels available.
