LTC3851AEUD-1#PBF Overview
It comes in the 16-WFQFN Exposed Pad package, which makes switching controller suitable for most applications. It is sufficient to generate 1 outputs with this dc motor controller. A solid enclosure of Tube surrounds pmic. With this function, you can deal with Transistor Driver dc switching's outputs (s). DC control operates at 4V~38V volts and has 4V~38V supply voltage. Suitable for a -40°C~125°C TJ dc switcher. There is a switch at 235kHz~750kHz that can be used with this controller. It is suitable for general dc dc regulator when it is set to Surface Mount. DCDC regulator is controlled efficiently by Enable, Frequency Control, Power Good, Soft Start, Tracking. A SWITCHING CONTROLLER analog integrated circuit is connected to the switch converters. The switching converters's terminal (s) are designed at QUAD . 16 terminations with various dc switching's functions. Some of the control techniques used by these dc dc converter ics are PULSE WIDTH MODULATION. 15V nominal DC switcher's voltage input. Other relevant dc to dc converter ics can be found by searching "LTC3851". Total pins of switching converter are 16. In particular, switching converter belongs to the Switching Regulator or Controllers family. The minimum input voltage of the dc dc voltage regulator should be 4V. DC regulator outputs 5.5V voltage according to the test statistics. Voltages 38V are the maximum that the dc to dc regulator will accept. DC regulators have a maximum frequency of 810kHz. For better satisfaction, the value of DC to DC voltage regulator is ALSO OPERATES IN ADJUSTABLE MODE FROM 0.8V TO 5.5V. The output value is set to the greatest value of 0.05A.
