LTC3859ALHUHF#PBF Overview
In the 38-WFQFN Exposed Pad package, the switching controller meets most application requirements. 3 outputs are supported by the dc motor controller. A solid enclosure of Tube surrounds pmic. The program can handle Transistor Driver dc switching's outputs (s). 4.5V~38V is the supply voltage and the operating voltage of the dc control. Work well in dc switchers with a -40°C~150°C TJ. A switching controller such as this can switch at a value of 115kHz~835kHz 350kHz~535kHz . As it has a Surface Mount value, it can be used for general dc dc regulator. DCDC regulator is controlled efficiently by Enable, Frequency Control, Power Good, Soft Start, Tracking. A SWITCHING CONTROLLER analog IC is connected to the switch converters. QUAD are the position of the terminal of the switching converters. A variety of terminations with 38 of dc switching. 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 12V. In addition to "LTC3859", there are other relevant dc to dc converter ics you can find. Switching converter is a type of Switching Regulator or Controllers in particular. 4.5V should be the minimum input voltage for the dc dc voltage regulator.
