LTC3891IFE#TRPBF Overview


Capsuled in the 20-TSSOP (0.173, 4.40mm Width) Exposed Pad package, the switching controller can be used for a wide range of applications. For 1 outputs, the dc motor controller is appropriate. PMIC is packaged in a solid enclosure of Tape & Reel (TR). Transistor Driver dc switching's outputs (s) can be handled by it. DC control operates at 4V~60V volts and has 4V~60V supply voltage. Worked in a -40°C~125°C TJ dc switcher before. There is a switch at 105kHz~835kHz 350kHz~535kHz that can be used with this controller. 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. Thare switch converters are connected to an analog integrated circuit (IC) of type SWITCHING CONTROLLER. Thare switching converters has a terminal (s) at DUAL . 20 terminations with various dc switching's functions. Some of the control techniques used by these dc dc converter ics are PULSE WIDTH MODULATION. The DC switcher's nominal voltage is 12V. You can find other relevant dc to dc converter ics by searching "LTC3891". Specially, switching converter corresponds to type Switching Regulator or Controllers. 4V should be the minimum input voltage for the dc dc voltage regulator. As determined by the test statistics, the output voltage of DC regulator is 5.1V. The dc to dc regulator can only accept 60V input voltage. This value is ALSO OPERATES IN ADJUSTABLE MODE FROM 0.80V TO 24V so that DC to DC voltage regulator better serves the purpose.
