LTC3854IDDB Product Details
LTC3854IDDB Overview
The switching controller fits in the 12-WFDFN Exposed Pad package and is ideal for most applications. dc motor controller is suitable for 1 output generation. Packaged in solid enclosures, this pmic has a Tube rating. There are Transistor Driver dc switching's output (s) that it can handle. A 4.5V~38V voltage is supplied to the dc control and used for operating it. Suitable for work in a -40°C~85°C TA dc switcher. With this switching controller, you can switch at 400kHz. The Surface Mount makes it ideal for general dc dc regulator. Featured in the dcdc regulator is Enable, Soft Start which allows efficient switching control. Thare switch converters are connected to an analog integrated circuit (IC) of type DUAL SWITCHING CONTROLLER. There are a terminal (s) on the switching converters that are designed at DUAL. 12 terminations with various dc switching's functions. The DC switcher's nominal voltage is 15V. Other relevant dc to dc converter ics will be returned if you search "LTC3854". Particularly, switching converter is a type of Switching Regulator or Controllers. It is recommended to use 4.5V as the minimum input voltage of dc dc voltage regulator. Considering the dc to dc regulator can only accept 38V input voltage, it is important to take note of this. In order to satisfy the need, DC to DC voltage regulator has a value of ALSO OPERATES IN ADJUSTABLE MODE FROM 0.8V TO 5.5V. Whenever the current value is 0.04A, switching converter outputs the highest possible value.
