Working Principles

The ACT4060ASH-T operates as a linear voltage regulator. It regulates the output voltage by comparing the feedback voltage (FB) with a reference voltage. The enable pin (EN) controls the operation of the IC. When enabled, the IC starts regulating the output voltage based on the feedback received. If the output voltage deviates from the desired value, the IC adjusts the internal circuitry to bring it back to the set level.
