LTC3851EUD-1#PBF Overview


This switching controller fits most application requirements since it is packaged in a 16-WFQFN Exposed Pad package. 1 outputs are supported by the dc motor controller. A solid enclosure of Tube surrounds pmic. With this function, you can deal with Transistor Driver dc switching's outputs (s). This dc control operates at 4V~38V and has a 4V~38V supply voltage. Work well in dc switchers with a -40°C~85°C TA. It can switch at 250kHz~750kHz. The Surface Mount allows it to be used for dc dc regulator in general. The dcdc regulator features Enable, Frequency Control, Power Good, Soft Start, Tracking for efficient switching control. SWITCHING CONTROLLER analog IC connects the switch converters. The switching converters's terminals (s) are designed at QUAD. 16 terminations with a variety of function. PULSE WIDTH MODULATION is an example of one of the control techniques these dc dc converter ics adapt. DC switcher's voltage input is 15V. A search for "LTC3851" will reveal other relevant dc to dc converter ics. There are a total of 16 pins on switching converter. Switching converter is a special type of Switching Regulator or Controllers. Input voltage of dc dc voltage regulator should be 4V. Based on the test statistics, DC regulator outputs voltage 5.5V. It should be noted that the dc to dc regulator only accepts 38V voltage as input voltage. In most cases, the dc dc regulator's output current is 25A. This information should be noted when you begin working with the component. The max frequency of the pmic can reach 790kHz. For better satisfaction, the value of DC to DC voltage regulator is ALSO OPERATES IN ADJUSTABLE MODE FROM 0.8V TO 5.5V.
