LTC3789IUFD#TRPBF Overview

In the 28-WFQFN Exposed Pad package, the switching controller meets most application requirements. For outputs of 2, this dc motor controller is suitable. Tape & Reel (TR) is the solid enclosure in which PMIC is packaged. It is capable of dealing with Transistor Driver dc switching's output (s). dc switching'sThe supply and operating voltage of the dc control are 4V~38V. Worked in an dc switcher with a -40°C~125°C TJ rating. The switching controller is capable of switching at the 200kHz~640kHz position. The Surface Mount value makes it suitable for general dc dc regulator. To ensure efficient switching, this dcdc regulator features a Current Limit, Enable, Frequency Control, Power Good, Soft Start. A SWITCHING CONTROLLER analog integrated circuit is connected to the switch converters. The switching converters's terminal (s) are designed at QUAD . A variety of terminations with 28 of dc switching. This dc dc converter ic uses a variety of control techniques, including PULSE WIDTH MODULATION. DC switcher's voltage input is 15V. LTC3789 can be used to locate other relevant dc to dc converter ics. The switching converter has a total of 28 pins. Switching converter is a special type of Switching Regulator or Controllers. An input voltage of 4V is the minimum required for the dc dc voltage regulator. A 38V voltage of DC regulator was detected in the test statistics. 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. Power-up and power-down reliability is ensured voltage regulator dc to dc by setting the maximum duty cycle to 90 %. This dc regulatorhas a max frequency of 710kHz. The value of DC to DC voltage regulator is set at ALSO OPERATES IN ADJUSTABLE MODE FROM 0.8V TO 38V in order to fulfill the requirements more effectively. There are 1 phases in this controller.
