LTC3731HUH#PBF 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. PMIC packaging is solid with a Tube enclosure. A total of Transistor Driver dc switching's outputs can be handled by it. The supply and operating voltage of the dc control are 3.8V~7V. Qualified to work in an dc switcher with -40°C~140°C TJ. With this switching controller, you can switch at 225kHz~680kHz. It is suitable for general dc dc regulator when it is set to Surface Mount. DCDC regulator is controlled efficiently by Enable, Phase Control, Power Good, Soft Start. An analog IC with the SWITCHING CONTROLLER signal is connected to the switch converters. There are a terminal (s) on the switching converters that are designed at QUAD. 32 terminations with various dc switching's functions. The control methods that these dc dc converter ics use include PULSE WIDTH MODULATION. DC switcher's voltage input is 5V. Other relevant dc to dc converter ics will be returned if you search "LTC3731". 32 pins are present on switching converter. There is a particular type of Switching Regulator or Controllers in switching converter. The dc to dc regulator can only accept 7V input voltage. There is a maximum frequency of 750kHz for this dc regulators. 5A is the largest value switching converter outputs. It belongs to the PolyPhase? series of dc to dc voltage regulator. In order to ensure high-quality communication, there are 1 channels available.
