LTC3851AEUD-1#TRPBF Overview


Capsuled in the 16-WFQFN Exposed Pad package, the switching controller can be used for a wide range of applications. It is sufficient to generate 1 outputs with this dc motor controller. The pmic is packaged in Tape & Reel (TR) solid enclosure. With Transistor Driver dc switching's output (s), it is able to handle it. A 4V~38V voltage is supplied to the dc control and used for operating it. Qualified to work in a -40°C~125°C TJ dc switcher. The switching controller can be switched at 235kHz~750kHz. The Surface Mount allows it to be used for dc dc regulator in general. To ensure efficient switching, this dcdc regulator features a Enable, Frequency Control, Power Good, Soft Start, Tracking. Thare switch converters are connected to an analog integrated circuit (IC) of type SWITCHING CONTROLLER. A switching converters's terminal (s) sits at the QUAD position. A variety of dc switching's functions can be performed on 16 terminations. It includes PULSE WIDTH MODULATION as one of the control techniques dc dc converter ic adapts. DC switcher's input voltageis 15V volts. Other relevant dc to dc converter ics can be found by searching "LTC3851". Pins number 16 of switching converter in total. Switching converter is a special type of Switching Regulator or Controllers. It is recommended that the dc dc voltage regulator's minimum input voltage be 4V. Statistically, DC regulator outputs 5.5V volts. At most, the dc to dc regulator accepts 38V input voltage. It is estimated that this dc regulatorhas a maximum frequency of 810kHz. Hence, ALSO OPERATES IN ADJUSTABLE MODE FROM 0.8V TO 5.5V is used to better suit the DC to DC voltage regulator's situation. The output value is set to the greatest value of 0.05A.
