LTC3851AEUD#PBF Overview
This switching controller fits most application requirements since it is packaged in a 16-WFQFN Exposed Pad package. The dc motor controller is adquate to generate for 1 outputs. The pmic is packaged in Tube solid enclosure. Transistor Driver dc switching's outputs (s) can be handled by it. 4V~38V is the supply voltage and the operating voltage of the dc control. Suitable for a -40°C~125°C TJ dc switcher. With this switching controller, you can switch at 235kHz~750kHz. Surface Mount makes it suitable for general dc dc regulator. Featured in the dcdc regulator is Current Limit, Enable, Frequency Control, Soft Start, Tracking which allows efficient switching control. Connected to a SWITCHING REGULATOR analog IC, the switch converters are connected to a power supply. switching converters terminal (s) are designed to be at QUAD. An array of 16 terminations 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 15V is input. Other relevant dc to dc converter ics can be found by searching "LTC3851". Pins number 16 of switching converter in total. The type is a particular Switching Regulator or Controllers of switching converter. Input voltage of dc dc voltage regulator should be 4V. Based on the test statistics, DC regulator outputs voltage 5.5V. At most, the dc to dc regulator accepts 38V input voltage. You should note that the dc dc regulator's usual output current is 25A. DC regulator's maximum frequency is 810kHz. Hence, ALSO OPERATES AS LDO REGULATOR, OPERATES IN ADJUSTABLE MODE FROM 0.8 TO 5.5V is used to better suit the DC to DC voltage regulator's situation.
