LTC3859AIUHF#PBF Product Details
LTC3859AIUHF#PBF Overview
With its 38-WFQFN Exposed Pad package, the switching controller fits the needs of most applications. For outputs of 3, this dc motor controller is suitable. Tube solid enclosure protects the pmic. It is capable of handling Transistor Driver dc switching's outputs (s). This dc control operates at 4.5V~38V and has a 4.5V~38V supply voltage. Worked in a -40°C~125°C TJ dc switcher before. In this switching controller, the switch can be set to 115kHz~835kHz 350kHz~535kHz. The Surface Mount allows it to be used for dc dc regulator in general. In order to control switching efficiently, the dcdc regulator features Enable, Frequency Control, Power Good, Soft Start, Tracking. DUAL SWITCHING CONTROLLER analog IC connects the switch converters. Switching converters are designed with the terminal (s) at position QUAD . The 38 terminations can be used for a wide range of dc switching. A few of the control techniques these dc dc converter ics adapt include PULSE WIDTH MODULATION. A DC switcher's nominal voltage of 12V is input. Searching "LTC3859" will return other relevant dc to dc converter ics. 38 pins are on switching converter. There is a particular type of Switching Regulator or Controllers in switching converter. Input voltage of dc dc voltage regulator should be 4.5V. Based on the test statistics, DC regulator outputs voltage 5.4V. If you are starting a new project, you should note the dc dc regulator's typical output current is 25A. There is a maximum frequency of 850kHz on this dc regulators.
