LTC3854EDDB Product Details

LTC3854EDDB Overview


This switching controller fits most application requirements since it is packaged in a 12-WFDFN Exposed Pad package. For 1 outputs, the dc motor controller is appropriate. A solid enclosure of Tube surrounds pmic. It is capable of handling Transistor Driver dc switching's outputs (s). This dc control has a supply voltage and operating voltage of 4.5V~38V. A -40°C~85°C TA dc switcher is not a problem. With this switching controller, you can switch at 400kHz. A generalization of dc dc regulator can be made using Surface Mount. To ensure efficient switching, this dcdc regulator features a Enable, Soft Start. Switch converters are connected to ICs with DUAL SWITCHING CONTROLLER analog outputs. Terminal (s) of the switching converters are designed at the DUAL position. 12 terminations with various dc switching's functions. A DC switcher's nominal voltage of 15V is input. Searching "LTC3854" will return other relevant dc to dc converter ics. Switching converter type is specifically Switching Regulator or Controllers. This dc dc voltage regulator should be powered by a voltage of 4.5V. The dc to dc regulator can only accept 38V input voltage. DC to DC voltage regulator has the value of ALSO OPERATES IN ADJUSTABLE MODE FROM 0.8V TO 5.5V to better satisfy the requirement. Current is output to the greatest value of 0.04A.
