LTC3856IFE Overview
With its 38-TFSOP (0.173, 4.40mm Width) Exposed Pad package, the switching controller fits the needs of most applications. There is sufficient capacity to generate switching controller for outputs 2. A solid enclosure of Tube surrounds pmic. With this function, you can deal with Transistor Driver dc switching's outputs (s). This dc control has a supply voltage and operating voltage of 4.5V~38V. Suitable for working in an dc switcher that has a -40°C~125°C TJ. In this switching controller, the switch can be set to 250kHz~770kHz. The Surface Mount value makes it suitable for general dc dc regulator. In order to control switching efficiently, the dcdc regulator features Current Limit, Enable, Frequency Control, Phase Control, Power Good, Soft Start, Tracking. The switch converters are connected to a SWITCHING CONTROLLER analog IC. DUAL are the position of the terminal of the switching converters. A variety of dc switching's functions can be performed on 38 terminations. A DC switcher's nominal voltage of 15V is input. Searching "LTC3856" will return other relevant dc to dc converter ics. Specifically, switching converter falls under the Switching Regulator or Controllers category. Input voltage of dc dc voltage regulator should be 4.5V. It should be fully noted that the dc to dc regulator only accepts 38V input voltage at most. Hence, ALSO OPERATES AS LDO REGULATOR, OPERATES IN ADJUSTABLE MODE FROM 0.6 TO 5V is used to better suit the DC to DC voltage regulator's situation. 0.1A is the greatest value switching converter outputs as current. Thare are switch converters of the PolyPhase? series.
