LTC3874IUF-1#PBF Overview


As a result of 24-WFQFN Exposed Pad compact design, the switching controller is compatible with most applications. dc motor controller is suitable for 2 output generation. The pmic is packaged in Tube solid enclosure. A total of Transistor Driver dc switching's outputs can be handled by it. The supply and operating voltage of the dc control are 4.5V~38V. Qualified to work in a -40°C~125°C TJ dc switcher. The switching controller can be switched at 250kHz~1MHz. The Surface Mount makes it ideal for general dc dc regulator. DCDC regulator is controlled efficiently by Current Limit, Enable, Frequency Control, Phase Control. The switch converters are connected to an analog IC with a SWITCHING CONTROLLER output. QUAD are the position of the terminal of the switching converters. Different dc switching's functions can be applied to 24 terminations. It includes PHASE-SHIFT CONTROL as one of the control techniques dc dc converter ic adapts. It is inputted with a DC switcher's voltage of 12V. LTC3874 can be searched for other relevant dc to dc converter ics. There are 24 pins on switching converter. An input voltage of 4.5V is the minimum required for the dc dc voltage regulator. Considering the dc to dc regulator can only accept 38V input voltage, it is important to take note of this. The dc to dc voltage regulator belongs to the PolyPhase? series. 5.5V represents the highest voltage output of the dc controller.
