LTC3857IUH#PBF Overview
It comes in a 32-WFQFN Exposed Pad package, so switching controller can be used for most applications. For 2 outputs, the dc motor controller is appropriate. There is a Tube solid enclosure around the pmic. A total of Transistor Driver dc switching's outputs can be handled by it. DC control operates at 4V~38V volts and has 4V~38V supply voltage. A -40°C~125°C TJ dc switcher is not a problem. Using this switching controller, it is possible to switch at 105kHz~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 Current Limit, Enable, Frequency Control, Phase Control, Power Good, Soft Start, Tracking. SWITCHING CONTROLLER analog IC connects the switch converters. QUAD are the position of the terminal of the switching converters. The 32 terminations can be used for a wide range of dc switching. These dc dc converter ics adapt several control methods, including PULSE WIDTH MODULATION. The nominal DC switcher's voltage input is 12V. Searching "LTC3857" will return other relevant dc to dc converter ics. Pins number 32 of switching converter in total. There is a particular type of Switching Regulator or Controllers in switching converter. Input voltage of dc dc voltage regulator should be 4V. DC regulator outputs 24V voltage based on test statistics. It should be noted that the dc to dc regulator only accepts 38V voltage as input voltage. 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. The dc to dc voltage regulator belongs to the PolyPhase? series. It is recommended that there be 1 channels for high-quality communication.
