LTC3891IUDC#TRPBF Overview


With a 20-WFQFN Exposed Pad package, the switching controller is suitable for a wide range of applications. It is sufficient to generate 1 outputs with this dc motor controller. Tape & Reel (TR) is the solid enclosure in which PMIC is packaged. With this function, you can deal with Transistor Driver dc switching's outputs (s). dc controls with 4V~60V voltage are supplied and operated. Qualified to work in an dc switcher with -40°C~125°C TJ. It can switch at 105kHz~835kHz 350kHz~535kHz. dc dc regulators can be carried out with Surface Mount. Current Limit, Enable, Frequency Control, Power Good, Soft Start, Tracking is used for efficient switching control in the dcdc regulator. SWITCHING CONTROLLER analog IC connects the switch converters. The switching converters's terminals (s) are designed at QUAD. 20 terminations with various dc switching's functions. Some of the control techniques used by these dc dc converter ics are PULSE WIDTH MODULATION. A DC switcher's nominal voltage of 12V is input. Other relevant dc to dc converter ics can be found by searching "LTC3891". Switching converter type is specifically Switching Regulator or Controllers. It is recommended that the input voltage of the dc dc voltage regulator be 4V. Test statistics indicate DC regulator outputs 5.1V voltage. This dc to dc regulator accepts only 60V input voltage at most. For better satisfaction, the value of DC to DC voltage regulator is ALSO OPERATES IN ADJUSTABLE MODE FROM 0.80V TO 24V.
