LTC3851EUD-1#TRPBF Overview
This switching controller fits most application requirements since it is packaged in a 16-WFQFN Exposed Pad package. For outputs of 1, this dc motor controller is suitable. Tape & Reel (TR) is the solid enclosure in which PMIC is packaged. A total of Transistor Driver dc switching's outputs can be handled by it. This dc control operates at 4V~38V and has a 4V~38V supply voltage. Suitable for working in an dc switcher that has a -40°C~85°C TA. The switching controller can be switched at 250kHz~750kHz. dc dc regulators can be carried out with Surface Mount. Enable, Frequency Control, Power Good, Soft Start, Tracking is used for efficient switching control in the dcdc regulator. SWITCHING CONTROLLER analog IC connects the switch converters. There are a QUAD terminal on the switching converters. A variety of 16 terminations are available in dc switching. PULSE WIDTH MODULATION is an example of one of the control techniques these dc dc converter ics adapt. DC switcher's input voltageis set to 15V. LTC3851 can be used to locate other relevant dc to dc converter ics. The type is a particular Switching Regulator or Controllers of switching converter. It is recommended to use 4V as the minimum input voltage of dc dc voltage regulator. Considering the dc to dc regulator can only accept 38V input voltage, it is important to take note of this. Hence, ALSO OPERATES IN ADJUSTABLE MODE FROM 0.8 TO 5.5 VOLT is used to better suit the DC to DC voltage regulator's situation. A value of 0.05A is output as the maximum value of current.
