LTC3854IMSE#PBF Overview


It comes in a 12-TSSOP (0.118, 3.00mm Width) Exposed Pad package, so switching controller can be used for most applications. For outputs of 1, this dc motor controller is suitable. The pmic is packaged in Tube solid enclosure. 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. Worked in an dc switcher with a -40°C~85°C TA rating. There is a switch at 400kHz that can be used with this controller. dc dc regulator can be generalized using Surface Mount. Switching control is made easier with the dcdc regulator's Enable, Soft Start. DUAL SWITCHING CONTROLLER analog IC connects the switch converters. Terminal (s) of the switching converters are designed at the DUAL position. 12 terminations with various dc switching's functions. The DC switcher's nominal voltage is 15V. LTC3854 can be searched for other relevant dc to dc converter ics. In total, switching converter has 12 pins. Particularly, switching converter is a type of Switching Regulator or Controllers. This dc dc voltage regulator should be powered by a voltage of 4.5V. The test statistics indicate that DC regulator outputs a voltage of 5.5V. It should be noted that the dc to dc regulator only accepts 38V voltage as input voltage. In most cases, the output current of the dc dc regulator will be 25A, so note that when you start the project. DC regulator440kHz has the maximum frequency. To better satisfy the need, DC to DC voltage regulator has a value of ALSO OPERATES IN ADJUSTABLE MODE FROM 0.8V TO 5.5V.
