LTC3855IUJ#PBF Product Details
LTC3855IUJ#PBF Overview
The switching controller fits in the 40-WFQFN Exposed Pad package and is ideal for most applications. dc motor controller is suitable for 2 output generation. Tube is the solid enclosure in which PMIC is packaged. With Transistor Driver dc switching's output (s), it is able to handle it. A 4.5V~38V voltage is supplied to the dc control and used for operating it. Worked in a -40°C~125°C TJ dc switcher before. It can switch at 250kHz~770kHz. A generalization of dc dc regulator can be made using Surface Mount. For efficient switching control, the dcdc regulator features Current Limit, Enable, Frequency Control, Phase Control, Power Good, Soft Start, Tracking. Connected to a DUAL SWITCHING CONTROLLER analog IC, the switch converters are connected to a power supply. There are a DUAL terminal on the switching converters. Various 40 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 15V. Searching "LTC3855" will return other relevant dc to dc converter ics. 40 pins are on switching converter. Switching converter type is specifically Switching Regulator or Controllers. An input voltage of 4.5V is the minimum required for the dc dc voltage regulator. A 12.5V voltage of DC regulator was detected in the test statistics. Voltages 38V are the maximum that the dc to dc regulator will accept. There is a maximum frequency of 850kHz on this dc regulators. Thare are switch converters of the PolyPhase? series. A high-quality communication requires 1 channels.
