LTC3854EMSE#TRPBF Overview
With its 12-TSSOP (0.118, 3.00mm Width) Exposed Pad package, the switching controller fits the needs of most applications. For 1 outputs, the dc motor controller is appropriate. Tape & Reel (TR) solid enclosure protects the pmic. With this function, you can deal with Transistor Driver dc switching's outputs (s). DC control operates at 4.5V~38V volts and has 4.5V~38V supply voltage. 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. The Surface Mount allows it to be used for dc dc regulator in general. To provide efficient switching control, Enable, Soft Start is included in the dcdc regulator. An analog IC with the DUAL SWITCHING CONTROLLER signal is connected to the switch converters. A switching converters's terminal (s) sits at the DUAL position. An array of 12 terminations of dc switching. DC switcher's input voltageis set to 15V. Other relevant dc to dc converter ics can be found by searching "LTC3854". There are a total of 12 pins on switching converter. Switching converter is a special type of Switching Regulator or Controllers. Input voltage of dc dc voltage regulator must be 4.5V. DC regulator outputs 5.5V voltage based on test statistics. Voltages 38V are the maximum that the dc to dc regulator will accept. If you start a project, note down the dc dc regulator's usual output current of 25A. 440kHz is the maximum frequency of this dc regulators. DC to DC voltage regulator has a value of ALSO OPERATES IN ADJUSTABLE MODE FROM 0.8V TO 5.5V to better satisfy the need.
