LTC3891EUDC#PBF Overview
With its 20-WFQFN Exposed Pad package, the switching controller fits the needs of most applications. It is sufficient to generate 1 outputs with this dc motor controller. Tube is the solid enclosure in which PMIC is packaged. With this function, you can deal with Transistor Driver dc switching's outputs (s). This dc control has a supply voltage and operating voltage of 4V~60V. A -40°C~125°C TJ dc switcher is not a problem. In this switching controller, the switch can be set to 105kHz~835kHz 350kHz~535kHz. Surface Mount makes it suitable for general dc dc regulator. To ensure efficient switching, this dcdc regulator features a Current Limit, Enable, Frequency Control, Power Good, Soft Start, Tracking. Switch converters are connected to ICs with SWITCHING CONTROLLER analog outputs. Thare switching converters has a terminal (s) at QUAD . A variety of terminations with 20 of dc switching. PULSE WIDTH MODULATION is an example of one of the control techniques these dc dc converter ics adapt. The DC switcher's nominal voltage is 12V. You can find other relevant dc to dc converter ics by searching "LTC3891". Switching converter is a special type of Switching Regulator or Controllers. The minimum input voltage of the dc dc voltage regulator should be 4V. As determined by the test statistics, the output voltage of DC regulator is 5.1V. A maximum voltage of 60V is accepted by the dc to dc regulator as an input voltage. DC to DC voltage regulator has the value of ALSO OPERATES IN ADJUSTABLE MODE FROM 0.80V TO 24V to better satisfy the requirement.
