LTC3891HFE#TRPBF Overview

With its 20-TSSOP (0.173, 4.40mm Width) Exposed Pad package, the switching controller fits the needs of most applications. It is sufficient to generate 1 outputs with this dc motor controller. An enclosure of Tape & Reel (TR) is used to package the PMIC. A total of Transistor Driver dc switching's outputs can be handled by it. This dc control has a supply voltage and operating voltage of 4V~60V. Qualified to work in a -40°C~150°C TJ dc switcher. A switching controller such as this can switch at a value of 105kHz~835kHz 350kHz~535kHz . As it has a Surface Mount value, it can be used for general dc dc regulator. Current Limit, Enable, Frequency Control, Power Good, Soft Start, Tracking is used for efficient switching control in the dcdc regulator. A SWITCHING CONTROLLER analog integrated circuit is connected to the switch converters. DUAL are the position of the terminal of the switching converters. An array of 20 terminations of dc switching. It includes PULSE WIDTH MODULATION as one of the control techniques dc dc converter ic adapts. DC switcher's input voltageis set to 12V. Other relevant dc to dc converter ics can be found by searching "LTC3891". In particular, switching converter is a type of Switching Regulator or Controllers. It is recommended to use 4V as the minimum input voltage of dc dc voltage regulator. A 5.1V voltage of DC regulator was detected in the test statistics. The dc to dc regulator can only accept a maximum input voltage of 60V. The value of DC to DC voltage regulator is set at ALSO OPERATES IN ADJUSTABLE MODE FROM 0.80V TO 24V in order to fulfill the requirements more effectively.
