LTC3855IUJ Overview


It comes in a 40-WFQFN Exposed Pad package, so switching controller can be used for most applications. There is sufficient capacity to generate switching controller for outputs 2. An enclosure of Tube is used to package the PMIC. A total of Transistor Driver dc switching's outputs can be handled by it. dc control's supply and operating voltages are 4.5V~38V. Suitable for working in an dc switcher that has a -40°C~125°C TJ. Using this switching controller, it is possible to switch at 250kHz~770kHz. It is suitable for general dc dc regulator when it is set to Surface Mount. In order to control switching efficiently, the dcdc regulator features Current Limit, Enable, Frequency Control, Phase Control, Power Good, Soft Start, Tracking. The switch converters are connected to an analog IC with a DUAL SWITCHING CONTROLLER output. Thare switching converters has a terminal (s) at DUAL . A variety of terminations with 40 of dc switching. To name a few of the control techniques these dc dc converter ics adapt, it includes PHASE-SHIFT CONTROL. A DC switcher's nominal voltage of 15V is input. In addition to "LTC3855", there are other relevant dc to dc converter ics you can find. Switching converter is a type of Switching Regulator or Controllers in particular. Input voltage of dc dc voltage regulator should be 4.5V. The dc to dc regulator is limited to 38V input voltage. It belongs to the PolyPhase? series of dc to dc voltage regulator.
