LTC3859AIUHF#PBF Overview


With a 38-WFQFN Exposed Pad package, the switching controller is suitable for a wide range of applications. 3 outputs can be generated with the dc motor controller. Tube solid enclosure protects the pmic. The program can handle 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. Switching control is made easier with the dcdc regulator's Enable, Frequency Control, Power Good, Soft Start, Tracking. A DUAL SWITCHING CONTROLLER analog integrated circuit is connected to the switch converters. Thare switching converters has a terminal (s) at QUAD . There are many different types of terminations for 38. These dc dc converter ics adapt several control methods, including PULSE WIDTH MODULATION. A DC switcher's nominal voltage of 12V is input. Searching "LTC3859" will return other relevant dc to dc converter ics. There are 38 pins on switching converter. In particular, switching converter belongs to the Switching Regulator or Controllers family. An input voltage of 4.5V is the minimum required for the dc dc voltage regulator. Test statistics indicate DC regulator outputs 5.4V voltage. If you are starting a new project, you should note the dc dc regulator's typical output current is 25A. The max frequency of the pmic can reach 850kHz.
