LTC3785EUF-1 Overview
The switching controller fits in the 24-WFQFN Exposed Pad package and is ideal for most applications. For outputs of 2, this dc motor controller is suitable. PMIC is packaged in a solid enclosure of Tube. Transistor Driver dc switching's outputs (s) are supported. Voltages 2.7V~10V are the dc control's supply voltage and operating voltage, respectively. Qualified to work in a -40°C~85°C TA dc switcher. In this switching controller, the switch can be set to 100kHz~1MHz. It is suitable for general dc dc regulator when it is set to Surface Mount. Featured in the dcdc regulator is Current Limit, Enable, Soft Start which allows efficient switching control. The switch converters are connected to a SWITCHING REGULATOR analog IC. Thare switching converters has a terminal (s) at QUAD . 24 terminations with a variety of function. These dc dc converter ics adapt a variety of control techniques, including PULSE WIDTH MODULATION. DC switcher's voltage input is 3.6V. A search for "LTC3785" will reveal other relevant dc to dc converter ics. The type is a particular Switching Regulator or Controllers of switching converter. 3A is the greatest value switching converter outputs as current.
