LTC3855EUJ Overview


Capsuled in the 40-WFQFN Exposed Pad package, the switching controller can be used for a wide range of applications. dc motor controller is suitable for 2 output generation. PMIC is packaged in a solid enclosure of Tube. The program can handle Transistor Driver dc switching's outputs (s). A 4.5V~38V voltage is supplied to the dc control and used for operating it. Suitable for a -40°C~85°C TA dc switcher. Using this switching controller, it is possible to switch at 250kHz~770kHz. dc dc regulator is made easier with Surface Mount. To ensure efficient switching, this dcdc regulator features a Current Limit, Enable, Frequency Control, Phase Control, Power Good, Soft Start, Tracking. An analog IC DUAL SWITCHING CONTROLLER is connected to the switch converters. Terminal (s) of the switching converters are designed at the DUAL position. An array of 40 terminations of dc switching. It includes PHASE-SHIFT CONTROL as one of the control techniques dc dc converter ic adapts. The DC switcher's nominal voltage is 15V. A search for "LTC3855" will reveal other relevant dc to dc converter ics. Particularly, switching converter is a type of Switching Regulator or Controllers. It is recommended to use 4.5V as the minimum input voltage of dc dc voltage regulator. Considering the dc to dc regulator can only accept 38V input voltage, it is important to take note of this. A dc to dc voltage regulator in the PolyPhase? series, it belongs to this family.
