LTC3789EUFD#PBF Overview
It comes in the 28-WFQFN Exposed Pad package, which makes switching controller suitable for most applications. The dc motor controller is adquate to generate for 2 outputs. PMIC packaging is solid with a Tube enclosure. With this function, you can deal with Transistor Driver dc switching's outputs (s). 4V~38V is the supply voltage and the operating voltage of the dc control. Suitable for work in a -40°C~125°C TJ dc switcher. Switching can be done at 200kHz~640kHz with this switching controller. As it has a Surface Mount value, it can be used for general dc dc regulator. Switching control is made easier with the dcdc regulator's Current Limit, Enable, Frequency Control, Power Good, Soft Start. A SWITCHING CONTROLLER analog IC is connected to the switch converters. Terminal (s) of the switching converters are designed at the QUAD position. 28 terminations with a variety of function. Some of the control techniques adapted by these dc dc converter ics include PULSE WIDTH MODULATION. It is inputted with a DC switcher's voltage of 15V. Other relevant dc to dc converter ics can be found by searching "LTC3789". 28 pins are on switching converter. Switching converter type is specifically Switching Regulator or Controllers. It is recommended to use 4V as the minimum input voltage of dc dc voltage regulator. As determined by the test statistics, the output voltage of DC regulator is 38V. 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. DC regulator's maximum frequency is 710kHz. DC to DC voltage regulator has a value of ALSO OPERATES IN ADJUSTABLE MODE FROM 0.8V TO 38V to better satisfy the need.
