LTC3891EFE#PBF Overview


As a result of 20-TSSOP (0.173, 4.40mm Width) Exposed Pad compact design, the switching controller is compatible with most applications. 1 outputs can be generated with the dc motor controller. PMIC is packaged in a solid enclosure of Tube. Transistor Driver dc switching's outputs (s) are supported. The supply and operating voltage of the dc control are 4V~60V. Suitable for working in an dc switcher that has a -40°C~125°C TJ. The switching controller is capable of switching at the 105kHz~835kHz 350kHz~535kHz position. It is suitable for general dc dc regulator when it is set to Surface Mount. The dcdc regulator features Current Limit, Enable, Frequency Control, Power Good, Soft Start, Tracking for efficient switching control. Thare switch converters are connected to an analog integrated circuit (IC) of type SWITCHING CONTROLLER. Terminal (s) of the switching converters are designed at the DUAL position. There are many different types of terminations for 20. PULSE WIDTH MODULATION is an example of one of the control techniques these dc dc converter ics adapt. There is a DC switcher's nominal voltage of 12V. Other relevant dc to dc converter ics will be returned if you search "LTC3891". There is a particular type of Switching Regulator or Controllers in switching converter. Input voltage of dc dc voltage regulator should be 4V. As determined by the test statistics, the output voltage of DC regulator is 5.1V. Voltages 60V are the maximum that the dc to dc regulator will accept. As a result, DC to DC voltage regulator has a value of ALSO OPERATES IN ADJUSTABLE MODE FROM 0.80V TO 24V so that the need can be met more directly.
