LTC3789IUFD#PBF Overview


With a 28-WFQFN Exposed Pad package, the switching controller is suitable for a wide range of applications. There is enough capacity in the dc motor controller to generate the output for the 2 input. Packaged in solid enclosures, this pmic has a Tube rating. With this function, you can deal with Transistor Driver dc switching's outputs (s). 4V~38V is the operating voltage and supply voltage of the dc control. Suitable for a -40°C~125°C TJ dc switcher. With this switching controller, you can switch at 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. The switch converters are connected to an analog IC with a SWITCHING CONTROLLER output. There are a QUAD terminal on the switching converters. A variety of 28 terminations are available in dc switching. The control methods that these dc dc converter ics use include PULSE WIDTH MODULATION. It is inputted with a DC switcher's voltage of 15V. LTC3789 can be used to locate other relevant dc to dc converter ics. In total, switching converter has 28 pins. Switching converter is a special type of Switching Regulator or Controllers. A 38V voltage of DC regulator was detected in the test statistics. If you are starting a new project, you should note the dc dc regulator's typical output current is 20A. DC regulator710kHz has the maximum frequency. For better satisfaction, the value of DC to DC voltage regulator is ALSO OPERATES IN ADJUSTABLE MODE FROM 0.8V TO 38V. In order to limit the voltage of a dc switcher whose maximum input voltage is 38V, it must be limited by the user. 4V is the required supply voltage. DC switchers cannot produce output currents greater than 5A. Datasheets indicate that the switching converter can output 38V volts at its maximum. Its lowest voltage output is not less than 800mV.
