LTC3859AIUHF#TRPBF Product Details
LTC3859AIUHF#TRPBF Overview
With a 38-WFQFN Exposed Pad package, the switching controller is suitable for a wide range of applications. The dc motor controller is adquate to generate for 3 outputs. There is a Tape & Reel (TR) solid enclosure around the pmic. There are Transistor Driver dc switching's output (s) that it can handle. 4.5V~38V is the supply voltage and the operating voltage of the dc control. Work well in dc switchers with a -40°C~125°C TJ. Switching can be done at 115kHz~835kHz 350kHz~535kHz with this switching controller. dc dc regulator can be generalized using Surface Mount. DCDC regulator is controlled efficiently by Enable, Frequency Control, Power Good, Soft Start, Tracking. The switch converters are connected to an analog IC with a DUAL SWITCHING CONTROLLER output. Thare switching converters has a terminal (s) at QUAD . 38 terminations with a variety of function. To name a few of the control techniques these dc dc converter ics adapt, it includes 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. Particularly, switching converter is a type of Switching Regulator or Controllers. Input voltage of dc dc voltage regulator should be 4.5V. Statistically, DC regulator outputs 5.4V volts.
