LTC3874EUF-1#PBF Overview

With a 24-WFQFN Exposed Pad package, the switching controller is suitable for a wide range of applications. There is enough capacity in the dc motor controller to generate the output for the 2 input. Packaging for the pmic consists of Tube solid enclosures. A total of Transistor Driver dc switching's outputs can be handled by it. 4.5V~38V is the supply voltage and the operating voltage of the dc control. Worked in an dc switcher with a -40°C~125°C TJ rating. Switching can be done at 250kHz~1MHz with this switching controller. As it has a Surface Mount value, it can be used for general dc dc regulator. To ensure efficient switching, this dcdc regulator features a Current Limit, Enable, Frequency Control, Phase Control. Thare switch converters are connected to an analog integrated circuit (IC) of type SWITCHING CONTROLLER. There are a QUAD terminal on the switching converters. Various 24 terminations. It includes PHASE-SHIFT CONTROL as one of the control techniques dc dc converter ic adapts. DC switcher's input voltageis 12V volts. Searching "LTC3874" will return other relevant dc to dc converter ics. In total, switching converter has 24 pins. It is recommended that the dc dc voltage regulator's minimum input voltage be 4.5V. The dc to dc regulator can only accept a maximum input voltage of 38V. PolyPhase? is a series of dc to dc voltage regulator. The dc controller's highest voltage output is tested at 5.5V.
