LTC3854EDDB#TRPBF Overview


The switching controller fits in the 12-WFDFN Exposed Pad package and is ideal for most applications. For 1 outputs, the dc motor controller is appropriate. A solid enclosure of Tape & Reel (TR) surrounds pmic. The system can process Transistor Driver dc switching's outputs (s). 4.5V~38V is the operating voltage and supply voltage of the dc control. Suitable for working in an dc switcher that has a -40°C~85°C TA. Switching can be done at 400kHz with this switching controller. A generalization of dc dc regulator can be made using Surface Mount. For efficient switching control, the dcdc regulator features Enable, Soft Start. DUAL SWITCHING CONTROLLER analog IC connects the switch converters. Switching converters are designed with the terminal (s) at position DUAL . There are many different types of terminations for 12. DC switcher's voltage input is 15V. Other relevant dc to dc converter ics will be returned if you search "LTC3854". In total, switching converter has 12 pins. In particular, switching converter is a type of Switching Regulator or Controllers. Input voltage of dc dc voltage regulator should be 4.5V. Statistically, the DC regulator outputs 5.5V voltage. It should be noted that the dc to dc regulator only accepts 38V voltage as input voltage. It's important to remember that the dc dc regulator's normaloutput current is 25A, so you should note it down when starting a new project. DC regulators have a maximum frequency of 440kHz. The value of DC to DC voltage regulator is set at ALSO OPERATES IN ADJUSTABLE MODE FROM 0.8V TO 5.5V in order to fulfill the requirements more effectively.
