LTC3789EUFD#TRPBF Overview

The switching controller fits in the 28-WFQFN Exposed Pad package and is ideal for most applications. There is enough capacity in the dc motor controller to generate the output for the 2 input. 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's4V~38V is the supply voltage and the operating voltage of the dc control. Workable in an dc switcher where -40°C~125°C TJ is the -40°C~125°C TJrm. A switching controller such as this can switch at a value of 200kHz~640kHz . The Surface Mount value makes it suitable for general dc dc regulator. Featured in the dcdc regulator is Current Limit, Enable, Frequency Control, Power Good, Soft Start which allows efficient switching control. An analog IC with the SWITCHING CONTROLLER signal is connected to the switch converters. The switching converters's terminals (s) are designed at QUAD. Various 28 terminations. This dc dc converter ic uses a variety of control techniques, including PULSE WIDTH MODULATION. 15V nominal DC switcher's voltage input. In addition to "LTC3789", there are other relevant dc to dc converter ics you can find. In total, switching converter has 28 pins. Particularly, switching converter is a type of Switching Regulator or Controllers. An input voltage of 4V is the minimum required for the dc dc voltage regulator. Statistically, DC regulator outputs 38V volts. It's important to remember that the dc dc regulator's normaloutput current is 20A, so you should note it down when starting a new project. It is estimated that this dc regulatorhas a maximum frequency of 710kHz. This value is ALSO OPERATES IN ADJUSTABLE MODE FROM 0.8V TO 38V so that DC to DC voltage regulator better serves the purpose.
