LTC3731CUH#TRPBF Product Details
LTC3731CUH#TRPBF Overview
It comes in a 32-WFQFN Exposed Pad package, so switching controller can be used for most applications. 3 outputs are supported by the dc motor controller. The pmic is packaged in Tape & Reel (TR) solid enclosure. Transistor Driver dc switching's outputs (s) can be handled by it. DC control operates at 3.8V~7V volts and has 3.8V~7V supply voltage. Suitable for work in a 0°C~70°C TA dc switcher. In this switching controller, the switch can be set to 225kHz~680kHz. The Surface Mount allows it to be used for dc dc regulator in general. In order to control switching efficiently, the dcdc regulator features Enable, Phase Control, Power Good, Soft Start. Thare switch converters are connected to an analog integrated circuit (IC) of type SWITCHING CONTROLLER. Terminal (s) of the switching converters are designed at the QUAD position. 32 terminations with a variety of function. These dc dc converter ics adapt several control methods, including PULSE WIDTH MODULATION. DC switcher's voltage input of 5V. In addition to "LTC3731", there are other relevant dc to dc converter ics you can find. The switching converter has a total of 32 pins. Particularly, switching converter is a type of Switching Regulator or Controllers. The minimum input voltage of the dc dc voltage regulator should be 4.5V. DC regulator's maximum frequency is 750kHz. Whenever the current value is 5A, switching converter outputs the highest possible value. It belongs to the dc to dc voltage regulator series PolyPhase?. In order to ensure high-quality communication, there are 1 channels available.
