LTC3859EUHF#TRPBF Overview


Capsuled in the 38-WFQFN Exposed Pad package, the switching controller can be used for a wide range of applications. For outputs of 3, this dc motor controller is suitable. An enclosure of Tape & Reel (TR) is used to package the PMIC. With this function, you can deal with Transistor Driver dc switching's outputs (s). dc controls with 4.5V~38V voltage are supplied and operated. Suitable for working in an dc switcher that has a -40°C~125°C TJ. Using this switching controller, it is possible to switch at 115kHz~835kHz 350kHz~535kHz. The Surface Mount value makes it suitable for general dc dc regulator. Enable, Frequency Control, Power Good, Soft Start, Tracking is used for efficient switching control in the dcdc regulator. A SWITCHING CONTROLLER analog IC is connected to the switch converters. Terminal (s) of the switching converters are designed at the QUAD position. A variety of terminations with 38 of dc switching. This dc dc converter ic uses a variety of control techniques, including PULSE WIDTH MODULATION. It is inputted with a DC switcher's voltage of 12V. A search for "LTC3859" will reveal other relevant dc to dc converter ics. There are only 38 pins on switching converter. There is a particular type of Switching Regulator or Controllers in switching converter. dc dc voltage regulators should have a minimum input voltage of 4.5V. As determined by the test statistics, the output voltage of DC regulator is 60V. The max frequency of the pmic can reach 850kHz. A high-quality communication requires 1 channels.
