Working Principles

LT3464ETS8#TRMPBF operates as a step-down voltage regulator. It takes an input voltage from the VIN pin and efficiently converts it to a lower, adjustable output voltage at the VOUT pin. The internal power switch controls the flow of current through an inductor (connected to the LX pin), which stores and releases energy to regulate the output voltage. The feedback pin (FB) allows the user to set the desired output voltage by connecting appropriate resistors. The enable pin (EN) can be used to turn the regulator on or off. The soft-start capacitor (SS) ensures a controlled startup, preventing excessive inrush current.
