LTC3859ALIUHF#PBF Overview
Capsuled in the 38-WFQFN Exposed Pad package, the switching controller can be used for a wide range of applications. This dc motor controller can be used to generate outputs with 3 numbers. Packaging for the pmic consists of Tube solid enclosures. It is capable of handling Transistor Driver dc switching's outputs (s). This dc control has a supply voltage and operating voltage of 4.5V~38V. Suitable for work in a -40°C~125°C TJ dc switcher. There is a switch at 115kHz~835kHz 350kHz~535kHz that can be used with this controller. The Surface Mount makes it ideal for general dc dc regulator. For efficient switching control, the dcdc regulator features Enable, Frequency Control, Power Good, Soft Start, Tracking. An analog IC SWITCHING CONTROLLER is connected to the switch converters. Thare switching converters has a terminal (s) at QUAD . There are many different types of terminations for 38. A few of the control techniques these dc dc converter ics adapt include PULSE WIDTH MODULATION. It is inputted with a DC switcher's voltage of 12V. Other relevant dc to dc converter ics will be returned if you search "LTC3859". Particularly, switching converter is a type of Switching Regulator or Controllers. Input voltage of dc dc voltage regulator should be 4.5V.
