LTC3854EMSE#PBF Product Details
LTC3854EMSE#PBF Overview
The switching controller fits in the 12-TSSOP (0.118, 3.00mm Width) Exposed Pad package and is ideal for most applications. This dc motor controller can be used to generate outputs with 1 numbers. Tube is the solid enclosure in which PMIC is packaged. With this function, you can deal with Transistor Driver dc switching's outputs (s). 4.5V~38V is the supply voltage and the operating voltage of the dc control. Work well in dc switchers with a -40°C~85°C TA. With this switching controller, you can switch at 400kHz. Surface Mount makes it suitable for general dc dc regulator. DCDC regulator is controlled efficiently by Enable, Soft Start. The switch converters are connected to an analog IC with a DUAL SWITCHING CONTROLLER output. There are a terminal (s) on the switching converters that are designed at DUAL. Various 12 terminations. A DC switcher's nominal voltage of 15V is input. A search for "LTC3854" will reveal other relevant dc to dc converter ics. In total, switching converter has 12 pins. Switching converter is a special type of Switching Regulator or Controllers. Input voltage of dc dc voltage regulator should be 4.5V. As determined by the test statistics, the output voltage of DC regulator is 5.5V. A maximum voltage of 38V is accepted by the dc to dc regulator as an input voltage. In most cases, the dc dc regulator's output current is 25A. This information should be noted when you begin working with the component. 440kHz is the maximum frequency of this dc regulators. Hence, ALSO OPERATES IN ADJUSTABLE MODE FROM 0.8V TO 5.5V is used to better suit the DC to DC voltage regulator's situation.
