Working Principles

The RT8097CLGE operates as a voltage regulator by converting the input voltage to a stable output voltage. It utilizes a switching regulator architecture to achieve high efficiency. The feedback voltage (FB) pin monitors the output voltage and adjusts the internal circuitry to maintain the desired output voltage. The enable control (EN) pin allows the IC to be turned on or off as required. The soft-start control (SS) pin ensures a gradual increase in output voltage during startup, preventing any sudden voltage spikes.
