Working Principles

The MAX16998AAUA+T is a voltage regulator that converts a higher input voltage to a lower output voltage. It utilizes a buck converter topology to achieve high efficiency power conversion. The device operates by controlling the duty cycle of an internal switch, which regulates the output voltage based on the feedback received from the FB pin.

When the EN pin is high, the regulator is enabled, and the output voltage is regulated according to the desired value set by external resistors connected to the FB pin. The SW pin is used to connect the inductor and capacitor required for energy storage and filtering.
