LTC3731IUH#TRPBF Overview


It comes in the 32-WFQFN Exposed Pad package, which makes switching controller suitable for most applications. This dc motor controller can be used to generate outputs with 3 numbers. An enclosure of Tape & Reel (TR) is used to package the PMIC. It is capable of dealing with Transistor Driver dc switching's output (s). dc switching'sThis dc control operates at 3.8V~7V and has a 3.8V~7V supply voltage. Worked in an dc switcher with a -40°C~85°C TA rating. The switching controller is capable of switching at the 225kHz~680kHz position. As it has a Surface Mount value, it can be used for general dc dc regulator. To ensure efficient switching, this dcdc regulator features a Enable, Phase Control, Power Good, Soft Start. An analog IC with the SWITCHING CONTROLLER signal is connected to the switch converters. A switching converters's terminal (s) sits at the QUAD position. Various 32 terminations. This dc dc converter ic uses a variety of control techniques, including PULSE WIDTH MODULATION. 5V nominal DC switcher's voltage input. You can find other relevant dc to dc converter ics by searching "LTC3731". 32 pins are on switching converter. The type is a particular Switching Regulator or Controllers of switching converter. 4.5V should be the minimum input voltage for the dc dc voltage regulator. DC regulators have a maximum frequency of 750kHz. A maximum value of 5A is output for current. A dc to dc voltage regulator in the PolyPhase? series, it belongs to this family. There are 1 channels for high-quality communication.
