LTC3855EUJ#PBF Overview
In the 40-WFQFN Exposed Pad package, the switching controller meets most application requirements. There is sufficient capacity to generate switching controller for outputs 2. Tube is the solid enclosure in which PMIC is packaged. With Transistor Driver dc switching's output (s), it is able to handle it. DC control operates at 4.5V~38V volts and has 4.5V~38V supply voltage. Qualified to work in an dc switcher with -40°C~85°C TA. A switching controller such as this can switch at a value of 250kHz~770kHz . The Surface Mount value makes it suitable for general dc dc regulator. To ensure efficient switching, this dcdc regulator features a Current Limit, Enable, Frequency Control, Phase Control, Power Good, Soft Start, Tracking. The switch converters are connected to a DUAL SWITCHING CONTROLLER analog IC. There are a terminal (s) on the switching converters that are designed at DUAL. A variety of 40 terminations are available in dc switching. A few of the control techniques these dc dc converter ics adapt include PHASE-SHIFT CONTROL. The nominal DC switcher's voltage input is 15V. LTC3855 can be searched for other relevant dc to dc converter ics. There are 40 pins on switching converter. In particular, switching converter is a type of Switching Regulator or Controllers. Input voltage of dc dc voltage regulator should be 4.5V. The test statistics indicate that DC regulator outputs a voltage of 12.5V. The dc to dc regulator is limited to 38V input voltage. It is estimated that this dc regulatorhas a maximum frequency of 850kHz. PolyPhase? is a series of dc to dc voltage regulator. Communication with high quality requires 1 channels.
