LTC3891HUDC#PBF Overview
With its 20-WFQFN Exposed Pad package, the switching controller fits the needs of most applications. For outputs of 1, this dc motor controller is suitable. Tube is the solid enclosure in which PMIC is packaged. It is capable of handling Transistor Driver dc switching's outputs (s). Voltages 4V~60V are the dc control's supply voltage and operating voltage, respectively. Qualified to work in an dc switcher with -40°C~150°C TJ. Switching can be done at 105kHz~835kHz 350kHz~535kHz with this switching controller. As it has a Surface Mount value, it can be used for general dc dc regulator. DCDC regulator is controlled efficiently by Current Limit, Enable, Frequency Control, Power Good, Soft Start, Tracking. A SWITCHING CONTROLLER analog integrated circuit is connected to the switch converters. The switching converters's terminals (s) are designed at QUAD. A variety of dc switching's functions can be performed on 20 terminations. The control methods that these dc dc converter ics use include PULSE WIDTH MODULATION. 12V nominal DC switcher's voltage input. Searching "LTC3891" will return other relevant dc to dc converter ics. In total, switching converter has 20 pins. Switching converter is a type of Switching Regulator or Controllers in particular. It is recommended to use 4V as the minimum input voltage of dc dc voltage regulator. Based on the test statistics, DC regulator outputs voltage 24V. At most, the dc to dc regulator accepts 60V input voltage. If you are starting a new project, you should note the dc dc regulator's typical output current is 5A. There is a maximum frequency of 835kHz for this dc regulators. DC to DC voltage regulator has the value of ALSO OPERATES IN ADJUSTABLE MODE FROM 0.80V TO 24V to better satisfy the requirement.
